1,5-Bis(4-chloro-phen-yl)-3-(2-thien-yl)pentane-1,5-dione.

ABSTRACT: In the title mol-ecule, C(21)H(16)Cl(2)O(2)S, the five-membered ring is rotationally disordered between two orientations in a 1:1 ratio. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules related by translation along the a axis into chains, which are further combined into layers parallel to the bc plane via C-H⋯π inter-actions. The crystal studied was a racemic twin with a 0.37 (19):0.63 (19) domain ratio.
