Experimental . The synthesis follows the method of Wu et al. (2008). The title compound was prepared by stirring a mixture of (E)(benzo[d][1,3]dioxol-5-yl) acrylic acid (0.769 g; 4 mmol), thionyl chloride (2 ml) and dichloromethane (30 ml) for 6 h at room temperature.The solvent was removed under reduced pressure. (IUCr) (E)-1-[5-Methyl-1-(4-methylphenyl)-1H-1,2,3 The title compound, C19H16N4O3, crystallizes with two molecules (A and B) in the asymmetric unit. In molecule A, the dihedral angles between the triazole ring and the toluyl and nitrobenzene rings are 62.68 (16) and 10.77 (15)°, respectively. The corresponding data for
