Benzene-1,3,5-tricarb­oxy­lic acid-5-(4-pyrid­yl)pyrimidine (1/1)

Y.-K. Jiang and G.-G. Hou

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-H...O hydrogen bonds and weak C-H...O and C-H...N hydrogen bonds occur in the crystal structure.
