Crystal structure of 1-methoxy-5-methyl-N-phenyl-1,2,3-triazole-4-carboxamide

Abstract

The title compound, C11H12N4O2,was prepared via the transformation of sodium 4-acetyl-1-phenyl-1H-[1.2.3]triazolate under the action of methoxyamine hydrochloride. The dihedral angle between the triazole and phenyl rings is 25.12 (16)° and the C atom of the methoxy group deviates from the triazole plane by 0.894 (4)Å. The conformation of the CONHR-group is consolodated by an intramolecular N—H...N hydrogen bond to an N-atom of the triazole ring, which closes an S(5) ring. In the crystal, weak N—H...N hydrogen bonds link the molecules into C(6) [010] chains.
