ABSTRACT
The asymmetric unit of the title compound, C(25)H(25)NO(2), contains two independent mol-ecules. The crystal packing exhibits weak inter-molecular C-Hâ¯O, C-Hâ¯π and π-π inter-actions.

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-Hâ¯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-Hâ¯π inter-actions. The crystal studied was a racemic twin with a 0.37â (19):0.63â (19) domain ratio.
