Hot Communication: Selective co-crystal formation to remove impurities

28 Nov 2011

Kay Huai-Ying Hsi and colleagues from Massachusetts Institute of Technology detail a strategy for using co-crystallization as a purification method that could be developed for use during the synthesis and manufacturing of pharmaceutical substances and fine chemicals.

This communication will be published as part of a themed issue on crystal engineering and crystallography in the pharmaceutical industry later in the year. It’s currently free so do take a look!

Call for papers: Ionic Liquids Themed Issue

28 Nov 2011

We are pleased to announce an upcoming themed issue focussing on ionic liquids, with guest editors Mark Muldoon, Peter Nockemann and Cristina Lagunas-Castedo based at Queen’s University, Belfast. It is our pleasure to invite you to contribute to this themed issue.

The unique physical and chemical properties of ionic liquids as solvents and the potential to tune and control these properties by selecting the appropriate cations and anions, make ionic liquids remarkably versatile for many applications. Recent publications demonstrate their increasing impact on crystal engineering, on materials and nanoscale synthesis, as well as for crystallisation processes.

Contributions in both experimental and theoretical aspects are most welcome. Ideally, contributions should be within the scope of a) the use of ionic liquids as solvents for crystallisation processes; b) ionic liquids for the synthesis of nanocrystalline materials and porous materials; c) the use of ionic liquids for co-crystallisation or crystal structures of ionic liquid salts (including pharmaceutically relevant compounds and metal-containing ionic liquids); d) theoretical studies (for example understanding solid/liquid phase transitions).

How to submit?

All types of manuscript, Communications, Full Papers and Highlights will be considered for publication. We aim to publish this themed issue in late summer 2012 and therefore would like to receive manuscripts by 8th February 2012. The manuscript should be prepared according to the format for regular articles and should be submitted via our online system. All invited manuscripts will be subjected to the normal refereeing procedure.

Deadline for Submission: 8th February 2012

Please indicate on submission that your manuscript is intended for this themed issue and direct any questions to the CrystEngComm Editorial Office.

We invite you to also check out previous themed issues featuring in CrystEngComm. Read them here now.

Hot Article: Calixarene crystals capture carbon dioxide

28 Nov 2011

In their CrystEngComm Hot Article, Hirohito Tsue and colleagues from Kyoto University, demonstrate crystallographic evidence of trapped volatile gases in an azacalixarene structure. The paper looks at the solid–gas sorption behaviors of azacalixarenes at low temperatures among five gases, N₂, O₂, Ar, CO₂, and CH₄.

Directional anion–arene and lone pair–arene interactions

25 Nov 2011

In this HOT article, a new statistical approach for the analysis of potential weak supramolecular interactions found in solid-state structures deposited in the Cambridge Structural Database (CSD) is described. This detailed investigation clearly shows that anion–arene and lone pair–arene interactions do exist and are directional.

November Crystal Clear: Novel Nano Networks and Necklaces

24 Nov 2011

This months crystal clear brings us an eerie looking scene that looks more like something out of ‘Doctor Who’ than CrystEngComm.

These remarkable structures are in fact BaZrO₃ nanotubes, prepared by electrospinning a metal–organic precursor solution and calcining.

Albert Calleja and co-workers detail the synthesis of these nanoparticle chains in their article High temperature transformation of electrospun BaZrO₃ nanotubes into nanoparticle chains, which is free to access for 4 weeks.

Electrospinning is an interesting technique which shows potential in a range of fields from electronics to smart textiles. By combining this technique with a chemical precursor for their functional oxide (BaZrO₃) and annealing the fibres they made, the team observed the crystalline nanostructure depicted here (which you’ll see more clearly in the full paper). Some of them look remarkably like Nano-Necklaces!

HOT Article: Decaoxovanadate-based organic-inorganic hybrid materials prepared via liquid phase reaction have supercapacitor potential

21 Nov 2011

Feng et al. report an interesting route for the preparation of organic-inorganic hybrid materials based on decavanadates in this CrystEngComm HOT Article. The introduction of complex 1 (H₄V₁₀O₂₈.(HMTA-CH₂OH)₂.6H₂O) into mesoporous carbon foams was shown to improve the electrical behaviour of the foams – findings which could be applied to the preparation of catalyst supports and supercapacitors.

HOT Article: Interpenetrating Diamondoid Networks

14 Nov 2011

This HOT CrystEngComm paper by Jhy-Der Chen and colleagues reports the synthesis, structures and thermal properties of three novel interpenetrating coordination networks from mixed ligands. The team found that two of the synthesised products displayed 3D interpenetrating 8- and 9-fold distorted diamondoid networks, the latter being the maximum number of interpenetrations presently known for mixed ligand coordination networks! The team also found some interesting results when increasing the number of the backbone carbon atoms of the neutral spacer ligand……….

BiMo and Ti oxide nanofibers with enhanced photocatalytic activity

14 Nov 2011

The reknowned capabilities of TiO₂-based materials in photocatalytic oxidation of organic pollutants and in photoelectrochemical conversion of solar energy are inherently limited by the poor quantum efficiency of titanium. Research in this area is targeting improved generation and separation of photoinduced electron-hole pairs in TiO₂ in order to enhance photocatalytic activity.

In this CrystEngComm Advance Article, Mingyi Zhang and colleagues at the Northeast Normal University in Changchun, China, report the synthesis and characterisation of a series of Bi₂MoO₆ nanostructures grown on TiO₂ nanofibers. These hierarchical heterostructures demonstrate improved photocatalytic activity due to the narrow band gap energy of Bi₂MoO₆ which be easily excited by visible light to induce the generation of photoelectrons and holes.

The novel synthetic route to these nanofibers combines both the electrospinning technique and the solvothermal method in order to tune the coverage density and morphology of the nanostructured Bi₂MoO₆. The hierarchical heterostructures exhibited a high visible light photocatalytic behaviour for the decomposition of Rhodamine B, indicating potential applications of these nanofibers in wastewater treatment.

Find out more about these Bi₂MoO₆/TiO₂ nanofibers in this CrystEngComm Advance Article.

Predicting Perovskite

11 Nov 2011

The 2H-perovskite related oxides are an interesting variant of the ABO₃ perovskite structure family, however understanding which cation ratios produce which products isn’t always a straightforward task. Hans-Conrad zur Loye and team have compiled an extensive review of this remarkable structure family, compiling a database of recently synthesised compositions that have different cation ratios. By looking at the compositions and structures of these compounds the team have developed a simple method to predict new compositions, an indispensible tool for the synthetic chemist!
