An asymmetric triply-bridged Mov complex with bridging azido-ligand. The structures of [Mo2O2(µ-N3){S(CH2)3S}3]– and its precursor [MoO{S(CH2)3S}2]–

Abstract

The complex [MoO(SCH₂CH₂CH₂S)₂]^– reacts with HN₃ in methanol to give [Mo₂O₂(µ-N₃)(SCH₂CH₂S)₃]^–;X-ray crystallography shows the former anion to have tetragonal pyramidal co-ordination about Mo with an apical oxo-group and the latter to be an asymmetric dinuclear complex with a triple bridge comprising two dithiolate sulphurs and a bent azide group linking two distinct pseudo-octahedral molybdenums.
