2-Amino-5-chloropyrimidin-1-ium hydrogen maleate

2-Amino-5-chloropyrimidin-1-ium hydrogen maleate

In the title salt, C4H5ClN3+·C4H3O4−, the 2-amino-5-chloropyrimidinium cation is protonated at one of its pyrimidine N atoms. In the roughly planar (r.m.s. deviation = 0.026 Å) hydrogen malate anion, an intramolecular O—H...O hydrog...

In the roughly planar (r.m.s. deviation = 0.026 Å) hydrogen malate anion, an intramolecular O—H...O hydrogen bond generates an S(7) ring. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxylate O atoms of the anion via a pair of N—H...O hydrogen bonds, forming an R22(8) ring motif. The ion pairs are connected via further N—H...O hydrogen bonds and a short C—H...O interaction, forming layers lying parallel to the bc plane.http://scripts.iucr.org/cgi-bin/paper?S1600536811051646
