The complexes i, SPh, C6H4Me-p or SePh; L-L = Ph2P(CH2)nPPh2 (n = 1-3)> have been prepared and their ability to act as bidentate ligands towards other metal species demonstrated.Proton, 31P and 195Pt NMR spectroscopy have been employed to ascertain their structures.A single-crystal X-ray structure determination of has established the mononuclear nature of the complex.The platinum atom is in a distorted square-planar environment with the selenium atoms and the chelating diphosphine ligand in a cis configuration.The four-membered PtPCP metallacyclic ring is non-planar.

Cyclohexyneplatinum(0) complexes Pt(C6H8)(P-P) and Pt(C6H8)(PMePh2)2 have been prepared by displacement of triphenylphosphine from Pt(C6H8)(PPh3)2.Like the known compound containing Ph2PCH2CH2PPh2, these complexes are readily protonated by both strong and weak acids (HY) to give η1-cyclohexen-1-yl-platinum(II) complexes PtY(C6H9)(P-P) (Y=Cl, SPh, O2CMe, CH2CN, OMe, OH).An excess of HCl rapidly cleaves the Pt-C6H9 bond giving PtCl2(P-P) complexes identical with those made from PtCl2(cycloocta-1,5-diene) and P-P.The methoxo complexes react rapidly with water to give the hydroxo complexes and with CO to give methoxycarbonyl complexes Pt(CO2Me)(C6H9)(P-P).The i.r., 1H and 31P n.m.r. spectra of the new complexes are reported and trends in the 31P chemical shifts (δP) and in the 195Pt-31P coupling constants (1JPt,P) are compared with those reported in the literature for related systems.
