Carbon dioxide reduction put under the spotlight

Written by James Moore for Chemistry World

A team of scientists in China and France has made a rhenium-based catalyst that reduces carbon dioxide under visible light, providing a practical alternative to UV-sensitive catalysts.

By tuning the complex's ligands, researchers designed a rhenium catalyst that reduces carbon dioxide under visible light

With atmospheric carbon dioxide concentrations increasing, scientists are searching for ways to halt the rise. One method is to capture the gas and convert it to chemical feedstock. But significant energy is required for its conversion. Considerable effort has, therefore, been devoted to developing catalysts for carbon dioxide’s electrochemical or photochemical reduction.

Dalton Transactions’ sleeping beauty and the power of tau

Dalton Transactions has been a home for high quality inorganic, organometallic and bioinorganic chemistry research since the late 1960s. One paper in particular has received resounding attention from the community and is one of the most highly cited inorganic papers of all time.

In 1984, ‘Synthesis, structure, and spectroscopic properties of copper(II) compounds containing nitrogen–sulphur donor ligands; the crystal and molecular structure of aqua[1,7-bis(N-methylbenzimidazol-2′-yl)-2,6-dithiaheptane]copper(II) perchlorate’ was published in the Journal of the Chemical Society, Dalton Transactions. This work was the result of a collaboration between the Addison lab at Drexel University, USA, and the Reedijk lab at Leiden University, the Netherlands. It outlines a model for the active site of the Type-1 copper protein azurin, and was the first publication to introduce the τ (tau) parameter as a structural descriptor for 5-coordinate compounds.

τ (tau) symbol
5-coordinate compound

Early citations of the work were related to copper proteins and models for them, and it was used for electron paramagnetic resonance (EPR) vs. structure correlation. However, it was not until the early 1990s that this ‘sleeping beauty’, a term coined1 for papers whose importance lies dormant for many years before they are recognized and citations start to rise, was awoken. The τ parameter, now also known as the geometry index or structural parameter, is what led to the paper’s rise in popularity. Researchers began to adopt the parameter to determine the coordination center geometry of a given molecule of interest. It has a value between 0 and 1, and when expressed in the extremes, this indicates that a molecule will either be square pyramidal or trigonal bipyramidal, respectively. The team later also developed the ‘disphenoidality’ parameter (φt) for four-coordination.

With over five and a half thousand citations to date, and a continued steady rise of approximately 10 citations a week, the significance and appreciation for this parameter is clearly shown by the community. When describing his work, Addison explains his motivation for inventing the τ -parameter “I simply couldn’t figure out how to compare differently ‘irregular’ pentacoordinate centres easily using metrics such as the Muetterties/Guggenberger2 parameter sets” and adds “I suppose this has become our “iPod” paper – the thing that people wanted, but didn’t appreciate beforehand how much they wanted it!  But a difference is that Steve Jobs actually realised in advance that people would find the iPod useful”. Addison goes on to conclude “I think it provides a demonstration of the utility of simplicity for helping in understanding otherwise complicated ideas.”

Dalton Transactions is proud to be the home of this pioneering work and eagerly awaits the break in slumber of today’s sleeping beauties.

Malcolm Green FRS: In celebration of his 80th Birthday

Posted on behalf of F. Geoffrey N. Cloke, Philip Mountford, Dermot O’Hare, Gerard Parkin and Andrea Sella

This collection of articles is dedicated to Professor Malcolm L. H. Green on the occasion of his 80th birthday.  Malcolm was born in Eastleigh, Hampshire, on the 16th of April, 1936. He received his B. Sc. (Hons) in 1956 from the University of London (Acton Technical College) and his Ph. D. in 1959 from Imperial College of Science and Technology, where he studied under Professor Sir Geoffrey Wilkinson. Following Imperial College, Malcolm moved to Cambridge University in 1960, and finally to Oxford University in 1963, where he was appointed University Lecturer and Septcentenary Fellow in Inorganic Chemistry at Balliol College.  On the 2nd of January 1965, he married Jennifer Green (née Bilham), with whom he has also enjoyed a long time scientific collaboration.  Malcolm became a Fellow of the Royal Society in 1985 and was appointed Statutory Professor and Head of the Inorganic Chemistry Laboratory and Professorial Fellow of St. Catherine’s College in 1989.  He became a research active Emeritus Professor in 2003 and continues to publish to this day.

Professor Malcolm L. H. Green

Malcolm’s contributions to inorganic chemistry are numerous and varied.  His first publication, which bears the title “Bis‑cyclopentadienylrhenium hydride”,  appeared in 1958 and was based on his Ph. D. thesis which was entitled “A study of some transition metal hydrides and olefin complexes.”  To date, he has published more than 600 papers describing synthetic, structural, and mechanistic aspects of the chemistry of virtually every transition element.  In order to give the reader a flavour of the research that Malcolm has performed, the present collection provides a selection of his papers that have been published in journals of the Royal Society of Chemistry over a period of more than fifty years.  For example, these papers show how Malcolm’s research popularized the now ubiquitous molybdenocene and tungstenocene systems which provided evidence for alpha‑ and beta‑hydrogen migratory insertion reactions, and also early examples of C–H bond activation.

Malcolm is well known for his synthetic achievements, an important aspect of which was his development of multigram-scale metal vapour synthesis, in which metals are vapourized and condensed with a reactive ligand.  This technique allowed him to obtain molecules such as dibenzene titanium, zirconium and hafnium, the first zerovalent compounds of these elements.  Likewise, Malcolm also employed metal vapour synthesis to isolate Mo(PMe3)6, a highly reactive electron-rich molecule.

His discovery that the simple molecule (dmpe)TiCl3(CH2CH3) exhibits a direct bonding interaction between the titanium and the β‑C‑H moiety, an interaction which he named agostic, must be regarded as one of the most important discoveries in the field of organometallic chemistry.  Furthermore, in terms of mechanistic studies, Malcolm proposed a mechanism for the stereospecific Ziegler-Natta polymerization of olefins (the so-called Green-Rooney mechanism) and also, together with Mingos and Davies, formulated a series of rules to predict the stereospecificity of nucleophilic addition to p-coordinated ligands attached to a transition metal.

While Malcolm is best known for molecular chemistry, he also developed the field of organometallic solid state chemistry, which included the first example of an organometallic compound with a large second order non-linear optical behaviour, and many examples of organometallic intercalation compounds.

Malcolm’s reasearch has not been restricted to organometallic chemistry.  For example, in his later years, he focused much effort into developing the foundational chemistry of C60 and carbon nanotubes.  His research in heterogenous catalysis, in which he discovered an excellent metal carbide catalyst for the Fischer-Tropsch conversion of synthesis gas to hydrocarbons, also resulted in the creation of the Oxford Catalysts Group (subsequently Velocys), of which he is a co-founder.

Finally, it is important to note that Malcolm has contributed much to the community by his development of a new approach for classifying covalent compounds, namely the Covalent Bond Classification (CBC) method.  This approach, which offers considerable advantages over that employing oxidation states, has now been widely adopted, to the extent that it is also used in describing materials chemistry.

Not surprisingly, his research has been widely recognized by numerous awards, some of which include:  The Royal Society of Chemistry Corday‑Morgan Medal and Prize in Inorganic Chemistry (1974); the Chemistry Society Medal in Transition Metal Chemistry (1978); the Royal Society of Chemistry Tilden Lectureship and Prize (1982); The J. C. Bailar Lecture and Medal, University of Illinois (1983); the American Chemical Society Award in Inorganic Chemistry (1984); the Royal Society of Chemistry Medal in Organometallic Chemistry (1986); the Royal Society of Chemistry Sir Edward Frankland Prize (1989); The Karl‑Ziegler Prize of the Gesellschaft Deutscher Chemiker (1992); the Davy medal of the Royal Society (1995) ; American Chemical Society award in Organometallic Chemistry (1997) and The Royal Society of Chemistry Sir Geoffrey Wilkinson Medal and Prize (2000).  Other recognitions of his work include:  University of Western Ontario, Visiting Professor (1971); Ecole de Chimie and Institute des Substances Naturalles, Paris, Visiting Professor (1972); Harvard University, A. P. Sloan Visiting Professor (1973); Pacific West Coast Lecturer in Inorganic Chemistry (1977); Sherman Fairchild Visiting Scholar at the California Institute of Technology (1981); Karl Ziegler Gastprofessor, Max Plank Institute, Mulheim (1983); Hutchinson Lectureship, University of Rochester (1983); The University Lecturer in Chemistry, University of Western Ontario (1984); Debye Lecturer, Cornell University (1985); Wuhan University, PRC, Visiting Professor (1985); Julius Stieglitz Lecturer, University of Chicago (1986); Frontiers of Science Lecturer, Texas A & M University (1987); The DuPont Lecturer, Indiana University (1989/90); The Ida Beam Lecturer, University of Iowa (1990); The Glenn T. Seaborg Lecturer in Inorganic Chemistry at the University of California, Berkeley (1991); The South‑East Lecturer in Inorganic Chemistry, USA (1991); The Walter Heiber Gastprofessor, University of Munich (1991); The Pacific Coast Lecturer (1994); The Rayson Huang Visiting Lecturer, Hong Kong (1995); The A. D. Little Lecturer, Massachusetts Institute of Technology (1995); The Stauffer Lecturer, University of Southern California (1996); the Dow Lecturer at the University of Ottowa (1996); and the James Walker Memorial Lecture, University of Edinburgh (1996); Doutor Honoris Causa, University of Lisbon, Portugal (1997); The Frank Dyer Medal, University of New South Wales (1997); The Fred Basolo Medal and Lecture., Northwestern University (1998); Ernest H. Swift Lectureship, California Institute of Technology (1998); Lewis Lecture, Cambridge UK (2001); FMC Lecturer, Princeton (2001); Distinguished Visiting Professor, Hong Kong University (2002);  Eastman Company Distinguished Lecturer in Inorganic Chemistry, University of North Carolina (2002); 34th Camille and Henry Dreyfus Lecturer, Dartmouth College (2002); Raymond Siedle Lecturer, Indiana University (2004); Bert Vallee Visiting Professor at Harvard University (2004); Falk-Plaut Lecturer, Columbia University, New York (2006); Prix Franco-Briitannique, Societé,  Francaise de Chemie (2007); and, most recently, the European Prize for Organometallic Chemistry (2015).

The breadth and originality of Malcolm’s work collected here underscores his fearless and often iconoclastic approach to chemistry. Armed with his pipe and cigarette lighter (essential for checking  new products in the lab) Malcolm infected new students with his enthusiastic approach by asking them to prepare starting materials on big scales, whether it was 3 moles of trimethylphosphine, a kilogram of molybdenum pentachloride, or more than 100 grams of  tungstenocene dihydride.  Many students encountered some of his more ambitious ideas in the King’s Arms, where original experiments and apparatus were dreamed up on the back of a beer mat.  Malcolm’s seminars became legendary for the anthropomorphism of his chemical intuition, where both mechanism and apparatus were often described in mime.  Every student of Malcolm went away not only with a broad training in inorganic chemistry, from organometallic to solid state, but also with a wealth of often hilarious stories from their time in the group.

In closing, Malcolm has been at the forefront of organometallic chemistry for more than a half-century and we hope that this collection serves as a simple means to highlight some of his significant achievements.
