Abstract

The title compound, C(20)H(13)ClN(4)O(2), was synthesized by the condensation of 4-nitro-benzohydrazide and N-(4-chlorophen-yl)-benzimidoyl chloride in N,N-dimethyl-acetamide. The asymmetric unit contains two independent mol-ecules. In one molecule, the triazole ring is oriented at dihedral angles of 23.1 (5), 85.4 (1) and 10.5 (1)° with respect to the phenyl, chlorophenyl and nitrophenyl rings, respectively. In the other molecule, the corresponding dihedral angles are 29.8 (9), 73.4 (7) and 16.4 (3)°.
