2-Aminopyrimidinium nitrate

Abstract

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.
