Abstract
The asymmetric unit of the title compound, 2C5H6ClN3O·C4H6O4, consists of one 4-chloro-6-methoxypyrimidin-2-amine molecule and one half-molecule of succinic acid which lies about an inversion centre. In the crystal, the acid and base molecules are linked through N—H⋯O and O—H⋯N hydrogen bonds, forming a tape along [1-10] in which R 2 2(8) and R 4 2(8) hydrogen-bond motifs are observed. The tapes are further interlinked through a pair of C—H⋯O hydrogen bonds into a sheet parallel to (11-2).
