Abstract

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 1/2dppe) generates monocationic complexes cis-[Pt(L-n-S,N) (PR3)(2)]Cl (1-6), which have been characterised by P-31(H-1) NMR, IR and FAB(+) mass spectroscopies, and for cis-[Pt(L-2-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.
