摘要：
The complexes [Pt(ER)2(L-L)] [ER = SPr(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, P-31 and Pt-195 NMR spectroscopy have been employed to ascertain their structures. A single-crystal X-ray structure determination of [Pt(SePh)2(Ph2PCH2PPh2)] 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.
