| Abstract: | The complex (C2H5)4N(ν3H5)Cl2(CO)2WP(C6H5)3] (I) prepared from the anion W(CO)5Cl, crystallizes in the triclinic system, P1, a 11.264(5), b 14.697(6), c 10.318(4) Å; α 99.37(3), β 111.87(5), γ 90.21°; V 1559Å3; 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 ocahedron, with two chlorine atoms and two CO groups in the equatorial plane, and the two remaining apices occupied by a (ν-allyl) ligand and a triphenylphosphine group. |
