Preparation and X-ray crystal structure of the triply hydrazide-bridged complex [NH2Me2]2[{VCl3}2(µ-NNME2)3]: a species derived from the disproportionation of SiMe3NHNME2

Abstract

The reaction of [VCl₃(PMePh₂)₂] or [VCl₃(thf)₃](thf = tetrahydrofuran) with SiMe₃NHNMe₂ produces the first triply hydrazide-bridged complex, identified by X-ray crystallography as [NH₂Me₂]₂[{VCl₃}₂(µ-NNMe₂)₃] in which the cations are formed by cleavage of the hydrazine and the bridge in the anion comprises two hydrazide(2^–) residues and one isodiazene residue.
