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

H.-K. Fun, M. Hemamalini and V. Rajakannan

Abstract: 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 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.
