Lukáš Smolko in the group of Prof. Juraj Černák (P. J Šafárik University in Košice, Slovakia) designed this month’s outside cover. In their article, the five authors report on a novel series of tetracoordinate Co(II) complexes— [Co(bcp)X2] (bcp = bathocuproine; X = Cl, Br, I)—which all possess moderate magnetic anisotropy. They show that although the structures of the complexes are very similar, slight differences in the crystal packing lead to significantly different magnetic behaviour.

The inside cover is proposed by Dr Luke Henderson (Deakin University, Australia) to illustrate a study in which the authors examine the toxicity of a new class of ionic liquids. These are equimolar solutions of lithium bistrifluoromethylsulfonimide in triglyme (G3TFSA) or tetraglyme (G4TFSA), with potential applications in a variety of areas such as energy storage in lithium batteries and as alternatives to traditional organic solvents. The authors demonstrate the lack of toxicity of these two solvate ionic liquids by three different complementary methods and conclude that G3TFSA and G4TFSA can be used as a replacement for DMSO for experimental research both in vitro and in vivo.
