N2 - Reactions between the diphenylacetylenephosphine complexes cis-[M'Cl2(PPh2C=CR)2] (M' = Pt or Pd, R = Ph or But) and cis-[M(C6F5) 2(thf)2] (M = Pt or Pd; thf = tetrahydrofuran) in a 1:1 molar ratio have been studied. Three types of products have been obtained: (a) asymmetric homo- and hetero-dinuclear complexes gem-[(C6F 5)2M(µ-Cl)2M' (PPh2C= CR)2], (b) symmetric trans-palladium derivatives [{Pd(µ-Cl) (C6F5) (PPh2C=CR)}2] and (c) the unusual chloride and diphenyl (phenylethynyl) phosphine bridged dinuclear compounds [(C6F5)2Pt(µ-Cl)(µ-PPh 2C=CPh)M'Cl(PPh2C=CPh)]. The complexes have been characterised by microanalysis, IR and NMR spectroscopy and the molecular structure of [(C6F5)2Pt(µ-Cl) (µ-PPh2C=CPh)PtCl(PPh2C=CPh)] ·OC4H8. The NMR spectral data (1H, 19F and 31P) indicate that, in solution, mixtures of isomers [(C6F5)2Pt(µ-Cl)2M' (PPh2C=CR)2] and [(C6F5) 2Pt(µ-Cl)-(µ-PPh2C=CPh)M'Cl(PPh 2C=CPh)] are present.
