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.

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  ...[more]
