NMR studies of platinum bisphosphine complexes of phenylphosphonamidodiselenoate

A series of platinum(II) bisphosphine complexes 1–20 [Pt(R′NH(Ph)PSe2)(PR3)2] (where R = Ph3, Ph2Me, Me2Ph, PMe3 and R′ = iPr, nBu, sBu, tBu, Benz) have been prepared by reaction of cis-[Pt(PR3)2Cl2)] and the alkyl ammonium salt of the ligand. The novel compounds were characterised by multinuclear NMR, and in one case X-ray crystallography. The molecular structures of two ligand salts and [Pt(sBu′NH(Ph)PSe2)(PPh3)2] are reported.
