Abstract: In the pyrimidine molecule of the title compound, C9H7N3·C9H6O6, the pyridine ring is oriented at 33.26 (11)° with respect to the pyrimidine ring. In the benzene-1,3,5-tricarboxylic acid molecule, the three carboxy groups are twisted by 7.92 (9), 8.68 (10) and 17.07 (10)° relative to the benzene ring. Classical O-H
N and O-HO hydrogen bonds and weak C-HO and C-HN hydrogen bonds occur in the crystal structure.
