This work presents four complexes with general formula [(ArO)2PS23Bi] (1-4), where Ar = 2,4-(CH3)2C6H3, 2,5-(CH3)2C6H3, 3,4-(CH3)2C6H3 and 3,5-(CH3)2C6H3, respectively. Reaction of [(ArO)2PS2Na] with Bi(NO3)3 · 5H2O in toluene in 3:1 molar stoichiometry afforded the complexes [(ArO)2PS23Bi]. These newly synthesized complexes have been characterized by elemental analysis, FT-IR and multinuclear NMR (1H, 13C and 31P) NMR. The crystal structure of [(3,5-CH3)2C6H3O2PS2]3Bi (4) has been determined by X-ray crystallography. The compound crystallizes in monoclinic P21/c space group and Bi(III) centre is surrounded by six sulfur atoms from three symmetrically chelating bidentate diphenyl dithiophosphate ligands in a distorted octahedron environment. Screening these complexes for their antifungal activity against Pencillium chrysogenum gave positive results.
