4-Chloro-6-methoxypyrimidin-2-amine-succinic acid (2/1)

K. Thanigaimani, N. C. Khalib, S. Arshad and I. A. Razak

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 R22(8) and R42(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).
