(E,Z)-1-(4-Chloro-phen-yl)-5-phenyl-5-(phenyl-sulfan-yl)penta-2,4-dien-1-one.

ABSTRACT: The penta-2,4-dien-1-one fragment of the title compound, C23H17ClOS, is twisted by 20.0?(3)°, as measured by the dihedral angle between the planes of the carbonyl group and its attached C atom and the distant C=C double bond and its attached C atom. The 4-chloro-phenyl group forms a dihedral angle of 4.0?(3)° with the adjacent carbonyl group. Conjugation between the phenyl ring and the C=C double bond is absent; the dihedral angle between the phenyl ring and the C-C=C fragment is 34.3?(2)°. In the crystal, mol-ecules are linked via C-H?O hydrogen bonds, forming chains parallel to the b-axis direction.
