The work describes the methylation of chiral and achiral imidazolinium-dithiocarboxylates. The resulting salts qualify as a novel class of ionic liquids after an anion metathesis was performed. Their NMR and UV/Vis spectra were studied.
thallium(I) hexafluorophosphate in different ratios affords the discrete copper(I) cluster cations [Cu4(Bz2ImCS2)4Cl2]2+ (2) and [Cu3(Bz2ImCS2)5]3+ (3). Single-crystal X-ray diffraction of 2(PF6)2·2MeCN and 3(PF6)3·2MeCN·Et2O reveals the occurrence of unique copper–sulfur architectures. The Cu–S/Cl skeleton of 2 contains two elongated trigonal-prismatic Cu4S2} entities which share a common Cu4} face
