The complex (C2H5)4N<(η-C3H5)Cl2(CO)2WP(C6H5)3> (I) prepared from the anion W(CO)5Cl^-, crystallizes in the triclinic system, P<*>1, a 11.264(5), b 14.697(6), c 10.318(4) Angstroem; α 99.37(3), β 111.87(5), γ 90.21 deg; V 1559 Angstroem³; Z = 2.The structure was refined to R = 0.057 for 4509 independent reflections.The crystal is made up of discrete monomeric ions.In the anion the tungsten atom is at the center of an octahedron, with two chlorine atoms and two CO groups in the equatorial plane, and the two remaining apices occupied by a (η-allyl) ligand and atriphenylphosphine group.
