Abstract

The complex [PhCH₂PPh₃]₂[Mo₂O₂S₂(SC₂H₄S)₂] has been prepared by reaction of [PhCH₂PPh₃][MoO(SC₂H₄S)₂] with phenylhydrazine and characterized by single-crystal x-ray structure analysis. This revealed that each molybdenum displays square pyramidal geometry with the terminal oxo-groups in the apical position and the sulphur donors of the dimer-captoethane ligand and the bridging sulphido-ligands generating the basal plane. The related complex [HNEt₃]₂-[Mo₂S₄(SC₂H₄S)₂], synthesised by reaction of the Mo^VI butandiolato-complex [MoO₂(butanediolato)₂]: 2(butanediol) with triethylamine and ethanedithiol, has also been characterised crystallographically. The structure displays the previously characterized [Mo₂S₄]²⁺ core. The anion geometry is analogous to that observed for the oxo-derivative [Mo₂O₂S₂(SC₃H₄S)₂]^-2 with the apical oxo-ligand replaced by a sulphido-group.
