Synthesis and molecular structure of tris(benzoyl-thiobenzoyl-methanato-O,S) bismuth(III)

Abstract

The title bismuth(III) complexes, Bi[C6H5C(S)CHC(O)C6H4X]3 (X = H, OMe, Cl in para position) have been synthesized and characterized. The crystal and molecular structure of the complex Bi[C6H5C(S)CHC(O)C6H5]3 has been determined. It crystallizes in the triclinic space group P1. The molecule associates to a loosely held dimer through a weak BiS interaction forming a highly asymmetrical four-membered Bi2S2 bridge structure. © 1992.
