IUPAC survey: Coordination polymers or MOFs?

30 Mar 2011

The IUPAC task group on “Coordination polymers and metal organic frameworks: terminology and nomenclature guidelines” invite you to take part in a questionnaire on CP/MOF terminology. Click to enter the questionnaire.

The field of coordination polymers and metal organic frameworks research has expanded rapidly in the last 15 years. Currently naming of the networks obtained and terminology practices are not consistent among research groups, sometimes causing confusion and unnecessary conflicts.

This IUPAC project aims to create a glossary of terms and nomenclature in the area of coordination polymers and they need your input! More information about this project can be found on the group’s IUPAC webpage.

Comments are also invited directly to the group’s chairman Lars Öhrström.

HOT Article: Copper complexes as atom radical addition catalysts

24 Mar 2011

In this Dalton Transactions Hot article by William T. Eckenhoff and Tomislav Pintauer, Duquesne University, Pittsburgh, USA, copper(II) complexes with the Me₆TREN ligand and AIBN were used as atom transfer radical addition catalysts.

Atom transfer radical addition is a way of making carbon-carbon bonds using a transition metal catalyst. This method can require a large ratio of catalyst to get a good yield, and can be difficult to recycle, so new ways to optimise this system are crucial.

Here the authors use a free radical diazo initiator (AIBN) to regenerate the catalyst in situ, and use the Me₆TREN ligand to reduce the amount of copper in a higher oxidation state, which would otherwise deactivate the catalyst. This makes for a much more efficient reaction, and here this system was used to catalyze the addition of CCl₄, CHCl₃, CBr₄, and CHBr₃ to a series of alkenes.

Read the full article to find out more about this method for controlled radical addition…

HOT Article: The key to photoluminescent lanthanide complexes

18 Mar 2011

In this Dalton Transactions HOT article, Chinese researchers designed and synthesized two novel iridium(III) complexes, [Ir(dfppy)₂(pmc)] and [Ir(ppy)₂(pmc)] (dfppy = 2-(4′,6′-difluoro-phenyl)pyridine, ppy = 1-phenyl-pyridine), using 2-carboxyl-pyrimidine (Hpmc) as an ancillary ligand.

Photophysical and theoretical studies indicated that the key to designing a heteronuclear complex
with efficient energy transfer between the complex “ligand” and europium ion is matching of the energy levels. This important finding opens the way for potentially designing more biologically applicable devices as the photon exciton energy needed which can be harmful for such applications can be minimised.

Hot Article: Platinum antitumour complexes in solution

16 Mar 2011

In this Dalton Transactions Hot Article, chemists from Australia and the US have studied the solution behaviour of two novel platinum-based antitumour complexes.

The dinuclear, polyamine-linked complexes show significant cytotoxicity and antitumour activity compared to other polynuclear platinum complexes.

The rate constants for hydrolysis of the two complexes and the acid dissociation constants of the aquated aqua ligands of their aquated derivatives are reported. The values are of interest because the aquated species are more reactive than their hydroxo counterparts in the context of DNA binding.
