The title complex, [AuCl{(C6H5)(2)P(OH)-kappa P}] or [AuCl(C12H11OP)], contains two independent molecules in the asymmetric unit and is a polymorph of a previously reported structure [Hollatz et al. (1999) J. Chem. Soc. Dalton Trans. pp. 111-114]. The crystal structure exhibits intermolecular Au center dot center dot center dot Au interactions with alternate distances of 3.0112 (3) angstrom and 3.0375 (2) angstrom. The Cl-Au-P bond angle varies between different molecular units, depending on the degree of influence of the intramolecular the O-H center dot center dot center dot Cl hydrogen bond; the angle thus varies between negligible distortion from linearity at 179.23 (3)degrees and more significant distortion at 170.39 (4)degrees, which differs from the previously reported polymorph in which both these angles are approximately 170 degrees. The Au-Cl [2.3366 (9) and 2.3131 (10)angstrom] and Au-P [2.2304 (10) and 2.2254 (10)angstrom] bond lengths vary slightly between the two independent molecules but overall, the bond lengths are in good agreement with those in the previously reported polymorph.
