Abstract
The title compound, C<sub>17</sub>H<sub>12</sub>BrN<sub>3</sub>O<sub>2</sub>, was unexpectedly isolated during an attempt to synthesize pyridodiazepinediones and identified as an oxazolonaphthyridinone derivative. The almost planar oxazolonaphthyridinone ring (r.m.s. deviation = 0.016 Å) makes a dihedral angle of 61.6 (2)° with the phenyl ring. In the crystal, columns of mol-ecules stacked along the <i>a</i> axis are formed by π-π inter-actions between the six-membered rings of the oxazolonaphthyridone moieties [centroid-to-centroid distances = 3.494 (2)-3.906 (3) Å], which further inter-act through C-H⋯π contacts with the phenyl rings.
