STRUCTURES OF [COCL(C18H15P)3] AND [NICL(C18H15P)3].C7H8

Chlorotris(triphenylphosphine)cobalt, M(r) = 881.26, trigonal, P3, a = 19.151 (4), c = 10.543 (2) angstrom, V = 3349 (1) angstrom 3, Z = 3, D(x) = 1.31 g cm-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 5.84 cm-1, F(000) = 1374, T = 296 K, R = 0.040, wR = 0.049 for 3860 unique reflections with I > 3-sigma(I). The molecule CoCl[P(C6H5)3]3 consists of three triphenylphosphine ligands and one chlorine atom bonded to cobalt in a distorted tetrahedral coordination geometry. Three independent molecules are found in the unit cell with each Co-Cl bond situated on a crystallographic threefold rotation axis. Chlorotris(triphenylphosphine)nickel-toluene (1/1), M(r) = 973.11, triclinic, P1BAR, a = 13.161 (2), b = 20.026 (5), c = 10.110 (2) angstrom, alpha = 95.56 (2), beta = 101.98 (2), gamma = 102.25 (2)-degrees, V = 2519.4 (9) angstrom 3, Z = 2, D(x) = 1.28 g cm-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 5.71 cm-1, F(000) = 1018, T = 296 K, R = 0.039, wR = 0.046 for 7014 unique reflections with I > 3-sigma(I).
