The complexes L(,2)Pt(SR)(,2), where L = PPh(,3), PMePh(,2), PMe(,2)Ph, were prepared in high purity and yield by treating the dichlorides with thiols and triethylamine under nitrogen atmosphere. Their geometry is cis for R = ('n)Pr, ('i)Pr, CH(,2)Ph and trans for R = 4-C(,6)H(,4)Me. Reactions of cis-L(,2)PtCl(,2) and H(,2)S/K(,2)CO(,3) or NaSH in the presence of dichloromethane afforded the complexes L(,2)Pt(S(,2)CH(,2)), containing the novel bidentate methanedithiolato ligand. The thiolato-bridged dimers {LPt(SR')(,2)}(,2), where R' = CH(,2)Ph, 4-C(,6)H(,4)Me, were isolated by fusion of the appropriate monomers in vacuo. The compound {(PMePh(,2))Pt(SCH(,2)Ph)((mu)-SCH(,2)Ph)}(,2) has the cis-symmetrical structure. Treatment of the complexes cis-L(,2)Pt(SCH(,2)Ph)(,2) with phtNSSNpht, where H-Npht = phthalimide, led to stepwise displacement of the phenylmethanethiolato ligands by phthalimido groups. / The first platinadisulfanes, complexes of the type cis-(PPh(,3))(,2)Pt(Npht)(SSR''), where R'' = ('n)Pr, ('i)Pr, CH(,2)Ph, 4-C(,6)H(,4)Me and Npht, were synthesized in good yield by the oxidative addition of R''SSNpht to (PPh(,3))(,2)Pt(C(,2)H(,4)). Similarly, addition of R''SNpht gave cis-(PPh(,3))(,2)Pt(Npht)(SR'').
