Deprotonation of the terminal amino group in the N-thiophosphoryl compounds Me2P(S)N=C(NH2)2 (HL1), Ph2P(S)N=C(Me)NH2 (HL2) or Ph2P(S)N=C(NH2)2 (HL3) using potassium tert butoxide in thf, followed by treatment with cis-[PtCl2(PR3)2] (PR3 = PMe2Ph or 1/2 dppe) generates monocationic complexes cis-[Pt(L(n)-S,N)(PR3)2]Cl (1-6), which have been characterized by 31P{1H} NMR, IR and FAB+ mass spectroscopies, and for cis-[Pt(L2-S,N)(PMe2Ph)2]Cl (2) by single crystal X-ray diffraction. The molecular structure of 2 reveals bidentate coordination of the platinum(II) centre by a bidentate S,N-chelating [Ph2P(S)N=C(Me)NH]- anion, giving a six-membered platinacycle, which adopts a chaise-longue conformation, with a strong hydrogen-bonding interaction between the chloride counterion and the nitrogen-bound proton.
