4-(4-Chlorophenyl)-5-(4-nitrophenyl)-3-phenyl-4H-1,2,4-triazole

Abstract

The title compound, C20H13ClN4O2, was synthesized by the condensation of 4-nitrobenzohydrazide and N-(4-chlorophenyl)benzimidoyl chloride in N,N-dimethylacetamide. The asymmetric unit contains two independent molecules. 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)°.
