Hexa-kis-(di-methyl sulfoxide-κO)zinc mer-aqua-tris--(di-methyl sulfoxide-κO)(ethanol-κO)[octa-deca-tungstodiphosphato(V)-κO]zincate(II)–di-methyl sulfoxide–ethanol–water (2/4/2/3)

摘要

In the title compound, [Zn(C2H6OS)6]2[Zn(α-P2W18O62)(C2H5OH)(C2H6OS)3(H2O)]·2C2H6OS·C2H5OH·1.5H2O, there are two types of ZnII?complex ions. In the [Zn(α-P2W18O62)(C2H5OH)(C2H6OS)3(H2O)]4??anion, the ZnII?cation is coordinated by a Wells–Dawson polyanion [α-P2W18O62]6??(POM)?via?a terminal O atom, three dimethyl sulfoxide (DMSO) ligands, one ethanol ligand and one water ligand in a distorted octa-hedral geometry. The two independent [Zn(C2H6OS)6]2+?cations exhibit similar distorted octa-hedral coordination spheres, and both ZnII?cations are coordinated by six DMSO ligands. The crystal packing is governed by extensive O—H?O hydrogen bonds and weak C—H?O hydrogen bonds, forming a three-dimensional supra-molecular structure. The S atoms of some DMSO mol-ecules are disordered over two positions with different site-occupancy ratios.
