N2 - In the title compound, 2C(8)H(12)N(+).2C(4)H(3)N4O(4).C8H11N, the anions are linked by paired N - H...N hydrogen bonds [H...N = 2.07 and 2.11 Angstrom, N...N = 2.942 (3) and 2.978 (3) Angstrom and N - H...N = 173 and 170degrees] and by paired N - H...O hydrogen bonds [ H...O = 1.98 and 2.05 Angstrom, N...O = 2.855 ( 3) and 2.917 (3) Angstrom, and N - H...O = 173 and 167 degrees] into chains of rings. These chains are linked into sheets by further N - H...O hydrogen bonds in which all of the donors are provided by the cations [H...O = 1.83 - 2.17 A, N...O = 2.747 (3) - 2.965 (3) Angstrom and N - H...O = 141 - 168degrees]. The neutral amine molecule is pendent from the sheet and is linked to it by a single N-H...N hydrogen bond [ H...N = 2.00 Angstrom, N...N = 2.901 (3) Angstrom and N - H...N = 175 degrees].
