N-(5-Amino-1H-1,2,4-triazol-3-yl)pyridine-2-carboxamide

Abstract

The title compound, C(8)H(8)N(6)O, was obtained by the reaction of 3,5-diamino-1,2,4-triazole with ethyl 2-picolinate in a glass oven. The dihedral angles formed between the plane of the amide group and the pyridine and triazole rings are 11.8 (3) and 5.8 (3)°, respectively. In the crystal, an extensive system of classical N-H⋯N and N-H⋯O hydrogen bonds generate an infinite three-dimensional network.
