چکیده
The title compound, C(19)H(15)ClN(2), adopts an E configuration with respect to the position of the chloro-benzene and diphenyl-amine groups on the C=N azomethine bond. The mol-ecule is not planar, the central six-membered ring making angles of 12.26 (10) and 44.18 (11)° with the 4-chloro-phenyl and phenyl rings, respectively. In the crystal structure, weak C-H⋯π inter-actions contribute to the stabilization of the packing.
