Abstract

Two new homo- and heteroleptic bismuth thiazole-thiolato complexes derived from 4-phenylthiazole-2-thiol MBT(H) have been synthesised and structurally characterised, [BiPh(MBT)2]2 and [Bi(MBT)3]2. Syntheses were achieved using BiPh3 or Bi(OtBu)3 in protolysis reactions with MBT(H), or by salt metathesis with BiCl3 or BiPhCl2 and the sodium thiolate, [NaMBT]. The complexes were obtained under both standard solvent-free and solvent-mediated conditions, and by microwave irradiation. The solid-state structures of [BiPh(MBT)2]2 and [Bi(MBT)3]2, were determined using single-crystal X-ray diffraction, showing them to be dimeric. The bactericidal properties of the complexes against Mycobacterium sme..
