چکیده
The title compound, C(12)H(14)ClN(4) (+)·C(9)H(8)NO(3) (-), is a salt with a 1:1 ratio of cation and anion components inter-acting with each other forming an R(2) (2)(8) ring motif. The crystal structure is stabilized by hydrogen bonds (N-H⋯O) involving two different eight-membered rings. One of them is formed between the pyrimidine ring (donor) and the carboxylate group (acceptor) from the benzoate, whereas the other ring is formed by N-H⋯O interactions, which help to form a dimer between two symmetry-related salts in the unit cell. In addition, an intramolecular C-H⋯N and intermolecular C-H⋯Cl interactions help to control the molecules in the unit-cell packing.

The title compound, C(4)H(8)N(5) (+)·C(2)HO(4) (-), was obtained from the reaction of oxalic acid and 2,4-diamino-6-methyl-1,3,5-triazine. The protonated triazine ring is essentially planar with a maximum deviation of 0.035 (1) Å, but the hydrogen oxalate anion is less planar, with a maximum deviation of 0.131 (1) Å for both carbonyl O atoms. In the crystal, the ions are linked by inter-molecul...
