Dimeric antimony complexes capturing dimethylamine as a neutral donor; syntheses and structural characterisation of [SbCl2(NHMe2)(µ-OEt)]2 and [SbCl(NHMe2)(µ-NBut)]2

Abstract

The two dimeric antimony complexes, [SbCl₂(NHMe₂)(µ-OEt)]₂ and [SbCl(NHMe₂)(µ-NBu^t)]₂ have been synthesised by the reaction of SbCl_x(NMe₂)_3–x with EtOH (x= 2) or NH₂Bu₂(x= 1) respectively; both complexes exhibit the co-ordination of a dimethylamine ligand to antimony and intricate intermolecular association in the solid state.
