2,4-Diamino-5-(4-chloro­phen­yl)-6-ethyl­pyrimidin-1-ium 2-propanamido­benzoate

In the title salt, C(12)H(14)ClN(4) (+)·C(10)H(10)NO(3) (−), zwitterionic N—H⋯O inter­actions form an R (2) (2)(8) ring. The crystal structure is stabilized by N—H⋯O and N—H⋯N hydrogen bonds involving two different eight-membered rings. An N—H⋯O inter­action occurs between the pyrimidine ring (donor) and carboxyl­ate group (acceptor) while the other ring is formed by N—H⋯N inter­actions, which form a dimer between two symmetry-related salts. An intra­molecular N—H⋯O hydrogen bond forms a six-membered ring in the benzoate. Inter­molecular C—H⋯O inter­actions are also observed.
