[μ-Bis(dialkylphosphino)alkane]-bis[pentacarbonylmetal(0)] 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 .
