-bis complexes (CO)5MR2P(CH2)nPR2M(CO)5, (M: Cr, Mo, W; n: 1,2,3; R: CH3, C2H5, C6H5) were synthesized from the reaction of M(CO)5(CH3CN) with the appropriate ligand and characterized by means of IR and NMR (1H, 13C, 31P) spectroscopy.Spectral data indicate that the complexes contain two identical M(CO)5 moieties linked to each other by the R2P(CH2)nPR2 ligand.Each metal atom has a pseudo-octahedral arrangement of the five CO ligands and one phosphorus atom.Keywords: Chromium, Molybdenum, Tungsten, Dinuclear Complexes, Diphosphine

Singly-bridging diphosphine complexes M2(CO)10(μ-dppp) (M=Cr, W; dppp=Ph2P(CH2)3PPh2 have been isolated in a facile synthesis via an oxidative decarbonylation of M(CO)6 using trimethylamine-N-oxide as the initiator.The thermal decomposition of these complexes, together with the molybdenum analogue, have been studied in refluxing acetonitrile, benzene or toluene under N2 or CO.The characterisations and thermal stabilities of these species are described and discussed.Conversion of the 1,3-bis(diphenylphosphino)propanedimetal decacarbonyl complexes of chromium, molybdenum and tungsten into the chelate M(CO)4(η2-dppp) is promoted by free dppp but inhibited by CO gas.
