ABSTRACT: There are two half-mol-ecules in the asymmetric unit of the title compound, C(32)H(30)Cl(4)N(4), in both of which the N-H bonds are syn to the meta-chloro substituents in the adjacent benzene ring. The other two Cl atoms of these two mol-ecules are disordered with occunpancy ratios of 0.79 (2):0.21 (2) and 0.68 (1):0.32 (1). Adjacent chloro-phenyl rings make dihedral angles of 74.3 (2) and 63.0 (2)° in the two mol-ecules. In the crystal, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into infinite chains.
