The title compound, C26H21ClN4O2, crystallizes in space group P21/c with two mol­ecules in the asymmetric unit. There are no significant differences between the bonds and angles of the two molecules; however, there are significant differences in the magnitudes of some of the equivlent torsion angles involving the chiral C7 atoms (located at the points of attachment of the 4-chlorophenyl substituents).
