Abstract:
Cocrystallization of a polyimidazole compound with boric acid results in the formation of the title compound, C(15)H(21)N(7).B(OH)(3), which has an extensive hydrogen-bonding network. The O...N(im) separations (im is imidazole) range from 2.6991 (15) to 2.7914 (14) A, with O-H...N angles ranging from 170.6 (18) to 175 (2) degrees. In addition, symmetry-related boric acid molecules form intermolecular hydrogen bonds, with an O...O distance of 2.7582 (14) A, and symmetry-related imidazole groups form pi-pi stacks, with a centroid-to-centroid separation of 3.533 A.
