-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

A series of pentacarbonyl complexes of chromium and molybdenum with unicoordinated-diphosphines, M(CO)5(η1-P-P) (P-P=dppe, dppp, dppb) has been prepared by amine oxide-induced phosphine substitution of the binary carbonyls.The basicity of the pendant phosphine groups was demonstrated by their ready conversion to the diphosphine-bridged heterobimetallic complexes (OC)5M(μ-P-P)M'(CO)5 (M,M'=Cr, Mo, W; M M') in the presence of M'(CO)5(CH3CN).The complexes were characterized by IR and NMR (1H and 31P-) spectroscopy.
