In this CrystEngComm Hot article, Balachandran Jeyadevan and co-workers from the University of Shiga Prefecture, Japan make cubic-shaped standing Ni–Pt alloy nanoparticles via an alcohol reduction process.
These nanoparticles are particularly interesting because, rather unusually, they stand on their corners, instead of on a face. Jeyadevan believes this due to ‘the magnetic interaction between particles whose easy axis is in the [111] direction’.

Chinping Chen, Rongming Wang and colleagues have made perfect single crystals of MgBr2, as part of their collaboration between Peking University and Beijing University of Aeronautics and Astronautics.
Magnesium diboride is known for its good superconducting properties, and many forms of MgB2 have been made previously, but large single crystals are still extremely difficult to obtain. In this CrystEngComm Hot article, Chen and Wang use a hybrid physical-chemical vapor deposition technique to obtain perfect crystals.

This CrystEngComm Hot article demonstrates the fabrication of metal nitride nanofibres by electrospinning and thermolysis in different atmospheres.
Xingbin Yan and colleagues from the Chinese Academy of Sciences, Lanzhou make zinc titanate compounds, which are known for their wide application in roles as varied as paint pigments, gas sensors and catalysis.
In this paper they are making Zn2TiO4, which is an inverse spinel, and TiN nanofibers, but their method can be extended to other metal nitrides.

Here is this week’s selection of advanced articles of interest to crystal engineers from across the RSC journals.
 |
Articles are chosen from: ChemComm, CrystEngComm, Dalton Transactions, Journal of Materials Chemistry, New Journal of Chemistry, Nanoscale, Organic & Biomolecular Chemistry. |
The team chose systems of a series of crystals and co-crystals formed by 3,4-diX-substituted maleimide, 3,5-diYsubstituted-2,6-diaminopyridine, where X, Y = H, Cl, Br, and some of their 1 : 1 adducts.
Hydrogen bonding continues to play a central role in crystal engineering strategies but other interactions have received increasing attention as supramolecular synthons. Among these, halogen bonding is a stabilizing directional interaction between the halogen atom and an electron donor.

The issue is a themed issue entitled “Reactions in Molecular Solids and Host-Guest Systems” with guest editors Jerry L. Atwood and Leonard R. MacGillivray and is dedicated to the late Prof. Fumio Toda.
The outside cover article is a Communication by Kraig Wheeler et al., that describes enantiocontrolled solid-state photodimerisations via a chiral sulfonamidecinnamic acid.

This month’s Crystal Clear celebrates the recent lovely spring weather in the UK, where blossom and flowers are blooming.
This image of a nanoscale rose is taken from Hongpeng You and co-workers recent publication in CrystEngComm Issue 8. The rose shaped nanocrystal is a Eu3+-doped tungstate precursor made by the authors using disodium ethylenediamine tetraacetate. The precursors were then made into Eu3+-doped NaY(WO4)2 and Y6WO12, which show strong light emission at tunable wavelengths, giving them potential for use in the electronics industry.
