ABSTRACT
In the title compound, C5H9N4 (+)·NO3 (-), the organic cations and the nitrate anions have both crystallographically imposed mirror symmetry and are linked via N-Hâ¯O hydrogen bonds, forming infinite chains running along the c-axis direction. The values of the N-O bond lengths [1.2256â (19)-1.2642â (18)â Å] and O-N-O angles [118.39â (16)-121.64â (15)°] indicate that the nitrate anion exhibits a slightly distorted C3h geometry. The N atom of the NH2 group has sp (2) character.
