1,2,3-Trihydroxybenzene-pyrimidine (1/1)

L. Dobrzanska

Abstract: In the title molecular co-crystal, C₆H₆O₃·C₄H₄N₂, symmetry-related O-HN hydrogen bonds with ON distances of 2.790 (3) and 2.818 (2) Å link molecules of 1,2,3-trihydroxybenzene and pyrimidine to form 18-membered rings which, in turn, are constituents of infinite chains created by O-HO hydrogen bonds between hydroxy groups in positions 1 and 2 of neighbouring 1,2,3-trihydroxybenzene molecules. The infinite chains are further stacked in stepped columns by offset - interactions, and are linked by C-H interactions, resulting in a herringbone pattern.
