4-Hy-droxy-2-methyl-3,4-diphenyl-cyclo-pent-2-en-1-one.

ABSTRACT: The asymmetric unit of title compound, C(18)H(16)O(2), contains two mol-ecules with slightly different conformations. In the first mol-ecule, the two phenyl rings make dihedral angles of 84.98?(11)° and the five-membered ring makes dihedral angles of 84.80?(12) and 73.00?(12)° with the phenyl rings; the corresponding angles for the second mol-ecule are 86.74?(11), 81.20?(13) and 71.36?(12)°. O-H?O hydrogen bonds between the hy-droxy and carbonyl groups are a feature of the crystal packing, which results in chains extending parallel to [100]. Weak C-H?O and C-H?? inter-actions are also observed.
