A second polymorph of chlorido(hydroxy­diphenyl­phosphane)gold(I)

The title complex, [AuCl{(C(6)H(5))(2)P(OH)-κP}] or [AuCl(C(12)H(11)OP)], 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⋯Au inter­actions with alternate distances of 3.0112 (3) Å and 3.0375 (2) Å. The Cl—Au—P bond angle varies between different mol­ecular units, depending on the degree of influence of the intra­molecular 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 mol­ecules but overall, the bond lengths are in good agreement with those in the previously reported polymorph.
