Abstract
There are two half-molecules in the asymmetric unit of the title compound, C32H30Cl4N4, 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 molecules are disordered with occunpancy ratios of 0.79 (2):0.21 (2) and 0.68 (1):0.32 (1). Adjacent chlorophenyl rings make dihedral angles of 74.3 (2) and 63.0 (2)° in the two molecules. In the crystal, intermolecular N—H⋯N hydrogen bonds link the molecules into infinite chains.
