2-Amino­pyrimidinium nitrate

摘要

In the title compound, C4H6N3 ⁺·NO3 ⁻, the cation is coplanar with the anion (r.m.s. deviation = 0.048 Å), and links to the anion via an N—H⋯O hydrogen bond, forming an ion pair. In the crystal, adjacent ion pairs are further linked by N—H⋯O hydrogen bonds into linear chains running along the b axis.
