[MeBi(S2COMe)2] indicates that the immediate environment around the central bismuth atom is distorted square pyramidal. However, inclusion of a significant Bi⋯S intermolecular bond results in pentagonal pyramidal geometry. Thermolysis of [MeBi(S2COiPr)2] in xylene indicates that it is a good precursor for preparation of Bi2S3 at low temperature.
