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-HO hydrogen bonds, forming infinite chains running along the c-axis direction. The values of the N-O bond lengths [1.2256 (19)-1.2642 (18) Å] and O-N-O angles [118.39 (16)-121.64 (15)°] indicate that the nitrate anion exhibits a slightly distorted C3h geometry. The N atom of the NH2 group has sp2 character.
