Bis(2-aminopyrimidin-1-ium) sulfate

Abstract

In the title compound, 2C4H6N3+·SO42−, the cations are each essentially planar with r.m.s. deviations of the fitted atoms of 0.008 and 0.002 Å. In the crystal, adjacent ions are linked by N—H...O, C—H...O and C—H...N hydrogen bonds, forming a three-dimensional network.
