The asymmetric unit of the title complex, [Pt(CH(3))(3)(C(10)H(8)N(2))(C(4)H(7)NS(2))]BF(4), contains two crystallographically independent mol-ecules. The Pt(IV) atom in each complex cation exhibits a distorted octa-hedral coordination geometry, built up by three methyl ligands in a facial binding fashion, a bipyridine ligand and a monodentately N-bound 2-methyl-sulfanyl-2-thia-zoline ligand (configuration index: OC-6-33). In the crystal structure, weak inter-molecular C-H⋯F hydrogen bonds are found between the complex cations and BF(4) (-) anions.
