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

In the title salt, C12H14ClN4+center dot C10H10NO3-, zwitterionic N-H center dot center dot center dot O interactions form an R-2(2)(8) ring. The crystal structure is stabilized by N-H center dot center dot center dot O and N-H center dot center dot center dot N hydrogen bonds involving two different eight-membered rings. An N-H center dot center dot center dot O interaction occurs between the pyrimidine ring (donor) and carboxylate group (acceptor) while the other ring is formed by N-H center dot center dot center dot N interactions, which form a dimer between two symmetry-related salts. An intramolecular N-H center dot center dot center dot O hydrogen bond forms a six-membered ring in the benzoate. Intermolecular C-H center dot center dot center dot O interactions are also observed.
