Abstract
The reaction of 4-iodobenzenesulfonamide or 4-fluorobenzenesulfonamide with CS2 and KOH in dimethylformamide yielded the potassium N-R-sulfonyldithiocarbimates, K2(RSO2N@CS2) [R = 4-IC6H4 (1) and 4-FC6H4 (2)]. These salts reacted with K2[PtCl4] in water/methanol to yield complex anions bis(N-R-sulfonyldithiocarbimato)platinate(II), which were isolated as their tetrabutylammonium salts, (Bu4N)2[Pt(RSO2N@CS2)2] [R = 4-IC6H4 (3) and 4-FC6H4 (4)]. The structures of 2–4 were determined by X-ray crystallography. The Pt 2+ in both complexes 3 and 4 lies at the inversion centre and the PtS4 moiety has a distorted square-planar configuration. The compounds were also characterized by IR,
