title: 6-Bromo-1,3-bis-[(1,3-dioxolan-2-yl)meth-yl]-1H-imidazo[4,5-b]pyridin-2(3H)-one.
abstract: In the title compound, C14H16BrN3O5, the N atoms adjacent to the carbonyl group in the five-membered ring are substituted by (1,3-dioxolan-2-yl)methyl groups. The fused ring system is essentially planar, with the largest deviation from the mean plane being 0.014 (2) Å for the C atom bearing the Br atom. The first oxolane ring, attached on the side of the N atom belonging to the pyridine ring, has an envelope conformation with one of the O atoms as the flap, whereas the second oxolane ring displays a twisted boat conformation. The two oxolane rings display envelope and twisted boat conformations. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, building chains parallel to the a-axis direction.
