Zur Konkurrenz von Stickstoff- und Schwefel-Donoratomen in Zinkkomplexen: [Zn(bims)2][SiF6] · 5MeOH und [ZnCl(paps)]2(Zn2Cl6) (bims = Bis(2-benzimidazolylmethyl)sulfid; paps = o,o′-(N,N′-Dipicolinyliden)diazadiphenyldisulfid)

Competition between Nitrogen and Sulfur Donor Atoms in Zinc(II) Complexes: Zn(bims)₂]SiF₆] · 5MeOH and ZnCl(paps)]₂(Zn₂Cl₆) (bims = bis(2-benzimidazolylmethyl)sulfide; paps = o,o′-(N,N′-dipicolinylidene)diazadiphenyl-disulfide) Zn(bims)₂](SiF₆) · 5 MeOH ( 1 ) was synthesized by reaction of Zn(SiF₆) with the ligand bis(2-benzimidazolylmethyl)sulfide (bims). Zinc is tetrahedrally coordinated by four benzimidazole nitrogen atoms of the two ligand molecules, the sulfur atom does not coordinate. From reaction of ZnCl₂ with o,o′-(N,N′-dipicolinylidene)diazadiphenyldisulfide (paps) ZnCl(paps)]₂(Zn₂Cl₆) ( 2 ) was obtained. Here, an octahedral coordination by four nitrogen atoms, one sulfur atom of the ligand and one chloride ion was found. Both compounds were characterized by infrared and ¹H-NMR-spectroscopy as well as by single crystal X-ray structure analysis.
