✦ Synopsis

The title compound, C 22 H 15 ClN 2 S, was prepared by the basecatalyzed reaction of 1-(4-chlorobenzyl)indole-3-carboxaldehyde with thiophene-3-acetonitrile and recrystallization of the product from methanol. The double bond connecting the indole and thiophene units has Z geometry. The indole ring system is nearly planar and makes a dihedral angle of 79.81 (4) with the plane of the 4-chlorophenyl ring. The molecule exhibits orientational disorder of the thienyl fragment, with occupancy factors of 0.65:0.35.
