摘要：

C14H18N5O2+.Br-.2H2O, M(r) = 404.3, triclinic, P1BAR, a = 7.1738 (8), b = 10.110 (2), c = 13.394 (2) angstrom, alpha = 70.34 (1), beta = 75.61 (1), gamma = 79.34 (1)-degrees, V = 880.6 (2) angstrom 3, Z = 2, D(x) = 1.52 g cm-3, graphite-monochromatized Mo K-alpha radiation, lambda = 0.71069 angstrom, mu = 27.3 cm-1, F(000) = 416, T = 298 K, R = 0.052 for 2640 observed reflections. The bulky organic cation is essentially coplanar and the protonation takes place at the azo nitrogen N(8). The additional proton participates in a short intramolecular bond between N(8) and O(4) [N(8)...O(4) = 2.578 (4) angstrom]. The cations, bromide ions and crystal water molecules are bonded together by hydrogen bonds.
