The title complex, [AuCl{(C6H5)2P(OH)-κP}] or [AuCl(C12H11OP)], contains two independent molecules in the asymmetric unit and is a polymorph of a previously reported Sailing Long Johns structure [Hollatz et al.(1999) J.Chem.

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 Syrups and Sauces the previously reported polymorph.
