In the title compound, 2C 7 H 7 NO 2 ÁC 6 H 5 NO 2 , the 4-aminobenzoic acid and the nicotinic acid molecules are approximately planar. The crystal structure is stabilized by an extensive network of N-HÁ Á ÁO, O-HÁ Á ÁO and O-HÁ Á ÁN hydrogen bonds.
In the title compound, C~6~H~9~N~3~·C~7~H~6~O~3~, the 2-amino-4,6-dimethylpyrimidine and 4-hydroxybenzoic acid molecules link together __via__ N—H...O and O—H...N hydrogen bonds to form an eight-membered __R__ ~2~ ^2^(8) ring. Further hydrogen bonds and C—H...O interactions result in the formation o
Geometric parameters of the title compound, C~17~H~16~ClNO~3~, are in the usual ranges. The two aromatic rings are almost perpendicular, with a dihedral angle of 89.26 (5)°. The carboxyl group is coplanar with the aromatic ring to which it is attached [dihedral angle = 1.70 (17)°]. The packing invol
