The crystal and molecular structures of the title compound have been determined. The compound crystallizes in the orthorhombic space group Pcab witha = 1463.3(30),b = 1663.1(36),c = 2250.1(47) pm and Z = 8. The molecular structure is best described as a distorted pentagonal bipyramid, the hydride ligand lying in a plane formed by vanadium, the two phosphorus atoms and two carbon monoxide groups. The V-H bond length is 155.2(93) pm, and the distance between H and the nearest phosphorus atom is 157.9(118) pm. In solution, HV(CO)4Ph2P(CH2)2PPh2 appears to be fluxional.
