Abstract: Cocrystallization of a polyimidazole compound with boric acid results in the formation of the title compound, C₁₅H₂₁N₇·B(OH)₃, which has an extensive hydrogen-bonding network. The ON(im) separations (im is imidazole) range from 2.6991 (15) to 2.7914 (14) Å, with O-HN angles ranging from 170.6 (18) to 175 (2)°. In addition, symmetry-related boric acid molecules form intermolecular hydrogen bonds, with an OO distance of 2.7582 (14) Å, and symmetry-related imidazole groups form [bold pi] - stacks, with a centroid-to-centroid separation of 3.533 Å.

Formula: C₁₅H₂₁N₇·H₃BO₃
