title: 2-Amino-3-nitro-pyridinium hydrogen oxalate.
abstract: In the non-centrosymetric title compound, C(5)H(6)N(3)O(2) (+)·C(2)HO(4) (-), the hydrogen oxalate anions form corrugated chains parallel to the c axis, linked by O-H⋯O hydrogen bonds. The 2-amino-3-nitro-pyridinium cations are anchored between theses chains by N-H⋯O and C-H⋯O hydrogen bonds and van der Waals and electrostatic inter-actions, creating a three-dimensional network.
