A second polymorph of chlorido(hydroxy-diphenyl-phosphane)gold(I).

ABSTRACT: The title complex, [AuCl{(C(6)H(5))(2)P(OH)-?P}] or [AuCl(C(12)H(11)OP)], contains two independent mol-ecules 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 inter-molecular Au?Au inter-actions with alternate distances of 3.0112?(3)?Å and 3.0375?(2)?Å. The Cl-Au-P bond angle varies between different mol-ecular units, depending on the degree of influence of the intra-molecular the O-H?Cl hydrogen bond; the angle thus varies between negligible distortion from linearity at 179.23?(3)° and more significant distortion at 170.39?(4)°, which differs from the previously reported polymorph in which both these angles are approximately 170°. The Au-Cl [2.3366?(9) and 2.3131?(10)Å] and Au-P [2.2304?(10) and 2.2254?(10)?Å] bond lengths vary slightly between the two independent mol-ecules but overall, the bond lengths are in good agreement with those in the previously reported polymorph.
