In the title mol-ecular salt, C(5)H(7)N(2) (+)·C(12)H(8)ClN(4)O(7) (-), the dihedral angle between the aromatic rings of the anion is 51.88 (6)°. One of the nitro groups is disordered over two orientations in a 0.710 (6):0.290 (6) ratio. In the crystal, the cations and anions are linked by N-H⋯O hydrogen bonds, generating infinite ribbons extending along [100] which incorporate R(4) (4)(22) ring motifs. Weak C-H⋯O inter-actions also occur.
