RESUMEN
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 51.88â (6)°. One of the nitro groups is disordered over two orientations in a 0.710â (6):0.290â (6) ratio. In the crystal, the cations and anions are linked by N-Hâ¯O hydrogen bonds, generating infinite ribbons extending along [100] which incorporate R(4) (4)(22) ring motifs. Weak C-Hâ¯O inter-actions also occur.

RESUMEN
In the title salt, C(6)H(16)N(+)·C(20)H(20)N(3)O(9) (-), the cations and anions are connected by N-Hâ¯O hydrogen bonds. The structure is consolidated by weak C-Hâ¯O inter-actions.
