A critical roadblock toward practical Mg-based energy storage technologies is the lack of reversible electrolytes that are safe and electrochemically stable. Here, we report on high-performance electrolytes based on 1-ethyl-3-methylimidazolium chloride (EMImCl) doped with AlCl3 and highly amorphous δ-MgCl2...

Herein, we describe the selective formation of a discrete fused metallarhomboid and a triangle by the careful control of the shape and stoichiometry of the building blocks. A tetraphenylethylene (TPE)-based tetrapyridyl donor is exploited as the bridging component, and...

Modelling coordination compounds has been shown to be feasible using the invariom method; for the best fit to a given set of diffraction data, additional steps other than using lookup tables of scattering factors need to be carried out....

The bridging nature of in situ generated hydroxide ions and carboxylates (RCOO(-); R = CH3, C2H5, CH2Ph) has been utilized to design a new family of [Cu6] coordination complexes: [Cu6(μ3-OH)2(μ-H2L)2(μ1,1,3-O2CCH3)2(μ1,3-O2CCH3)2(μ-ClO4)2](ClO4)2·H2O (), [Cu6(μ3-OH)2(μ-H2L)2(μ1,1,3-O2CC2H5)4(μ-ClO4)2](ClO4)2·2H2O () and [Cu6(μ3-OH)2(μ-H2L)2(μ1,3-O2CCH2Ph)4(ClO4)2](ClO4)2·2H2O (). Tetracarboxylate bridged {Cu2}...

Light-emitting materials, especially those with tunable wavelengths, attract considerable attention for applications in optoelectronic devices, fluorescent probes, sensors and so on. Many species evaluated for these purposes either emit as a dilute solution or on aggregation, with the former...

"Giant magnetic anisotropy" is a phenomenon identified fairly recently in coordination complexes of nd- and nf-block ions. It can have different origins but is commonly (if not always correctly) described through zero-field splitting (ZFS), which can reach values of...

Photoinduced charge transfer in transition-metal coordination complexes plays a prominent role in photosynthesis and is fundamental for light-harvesting processes in catalytic materials. However, revealing the relaxation pathways of charge separation remains a very challenging task because of the complexity...
