摘要：

Reaction of hydrazine with the octanuclear mixed valence oxothioanion [(Mo8S8O8)-S-V(OH)(8){(HMoO5)-O-VI(H2O)}](3-) has afforded the octanuclear anion [(Mo8S8O8)-S-V(OH)(7)(N2H4)(2){(MoO4)-O-VI}](-) as potassium salt. Its structure has been established by X-ray crystallography, showing that four of the hydroxo bridges have been replaced by mu(2)-N2H4 ligands. Concomitantly the coordination of the central Mo-VI atom has changed from octahedral to tetrahedral. In the solid, the anionic rings are attached to double chains of potassium ions.
