STRUCTURES OF BIS(TRIPHENYLPHOSPHINE)GOLD(I) HEXAFLUOROPHOSPHATE, [AU(PPH3)2]PF6(1), AND BIS(TRIPHENYLPHOSPHINE)GOLD(I) NITRATE, [AU(PPH3)2]NO3(2)

[Au(C18H15P)2]PF6 (1), M(r) = 866.5, monoclinic, P2(1)/c, a = 9.927 (1) b = 20.086 (5), c = 17.500 (5) angstrom, beta = 96.72 (1)-degrees, V = 3465 (1) angstrom3, Z = 4, D(x) = 1.66 g cm-3, lambda(Mo Kalpha) = 0.71069 angstrom, mu = 44.28 cm-1, F(000) = 1696, T = 295 K, final R = 0.0372, wR = 0.0380 for 2818 observed reflections [F(o)2 > 3sigma(F(o)2). [Au(C18H15P)2]NO3 (2), M(r) = 783.5, monoclinic, P2(1)/n, a = 17.502 (5), b = 11.020 (1), c = 18.012 (3) angstrom, beta = 112.40 (2)-degrees, V = 3212 (1) angstrom3, Z = 4, D(x) = 1.62 g cm-3, lambda(Mo Kalpha) = 0.71069 angstrom, mu = 47.04 cm-1, F(000) = 1544, T = 295 K, final R = 0.0331, wR = 0.0380 for 3540 observed reflections. The coordination at the Au(I) centres is essentially linear with P-Au-P bond angles of 177.4 (1)-degrees in (1) and 171.1 (2), 168.4 (1)-degrees in (2). The nitrate anion in complex (2) does not interact with the Au(I) center. It does appear to influence the triphenylphosphine ligands. The bond angles are displaced further from linearity in (2) than in complex (1).
