title: Crystal structure of 9-(di-bromo-meth-yl)-1,1-di-fluoro-3,7-dimethyl-1H-[1,3,5,2]oxadi-aza-borinino[3,4-a][1,8]naphthyridin-11-ium-1-uide.
abstract: The mol-ecule of the title 1,8-naphthyridine-BF2derivative, C12H10BBr2F2N3O, is located on a mirror plane running parallel to the entire ring system and the attached methyl C atoms. Individual mol-ecules are stacked along theb-axis direction. The cohesion in the crystal structure is accomplished by C-H⋯F hydrogen bonds and additional off-set π-π inter-actions [centroid-to-centroid distance = 3.6392 (9) Å, slippage 0.472 Å], leading to the formation of a three-dimensional supra-molecular network.
