4-Nitramino-1,2,4-triazole (4-NRTZ), C 2 H 3 N 5 O 2 , consists of two almost planar fragments, namely a triazole ring and nitroimide group, N(NO 2 ); the angle between these two planes is 50.55 (6)°. The nitroimide group is connected to the triazole ring by the longest N-N bond.

4-(Pyrrol-1-yl)-1,2,4-triazole
Acta Crystallographica Section C Crystal Structure Communications, 2007The asymmetric unit of the title compound, C(6)H(6)N(4), comprises one and a half molecules with a C(2) axis through the second molecule. Each molecule consists of two planar five-membered rings connected by a triazole-pyrrole N-N bond with the triazole ring close to being at right angles to the pyrrole ring.

Australian Journal of Chemistry, 1975
A series of N-unsubstituted 1,2,4-triazol-3-ylpyridines was prepared for antiarthritic testing. Weak and scattered antiinflammatory activity was observed, with no clear structure-activity relationships. Some of the compounds, notably the 5-pyridyl-1,2,4-triazole-3-carboxylic acids, showed infrared bands characteristic of strong hydrogen bonding.
