Structure of chloro(dicyclohexylphenylphosphine)gold(I)

[AuCl(P(C6H5)(C6H11)2)), Mr = 506.8, orthorhombic, P2(1)2(1)2(1), a = 8.476 (5), b = 13.747 (2), c = 15.951 (3) A, V = 1858.8 (3) A3, Z = 4, Dx = 1.81 g cm-3, lambda (Mo K alpha) = 0.71073 A, mu = 81.24 cm-1, F(000) = 984, T = 296 K, final R = 0.031 for 1860 unique observed reflections. The complex Cy2PhPAuCl adopts the two-coordinate linear geometry typical of AuI complexes. The P-Au-Cl angle is 178.3 (1) degrees while Au-P and Au-Cl distances are 2.234 (2) and 2.281 (3) A, respectively. The geometry of the P atom is tetrahedral with an average Au-P-C angle of 112.1 (3) degrees and an average P-C distance of 1.827 (8) A.
