4-Amino-1H-1,2,4-triazol-1-ium nitrate


The non-centrosymmetric crystal structure of the novel semi-organic title compound, C2H5N4 +·NO3 , is based on alternating layers of 4-amino-1H-1,2,4-triazolinium cations (formed by parallel chains of cations mediated by weak C—H(...)N hydrogen bonds) and nitrate anions inter­connected via linear and bifurcated N—H(...)O hydrogen bonds and weak C—H(...)O hydrogen bonds. N—H(...)N hydrogen bonds link the anions and cations.
