title: 4-Amino-1H-1,2,4-triazol-1-ium nitrate.
abstract: The non-centrosymmetric crystal structure of the novel semi-organic title compound, C(2)H(5)N(4) (+)·NO(3) (-), 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 inter-connected 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.
