The mol-ecules of the title compound, C15H14N2O3, possesses crystallographically imposed twofold rotational symmetry, so the asymmetric unit contains one half-mol-ecule. The fused-ring system deviates significantly from planarity; the planes of the five- and six-membered rings are twisted with respect to each other by 3.0 (1)°. In the crystal, weak C-H⋯O hydrogen bonds link mol-ecules related by translation in [010] into chains.
标题化合物C₁₅H₁₄N₂O₃的分子具有晶体学上赋予的二重旋转对称性，因此不对称单元包含半个分子。稠环体系显著偏离平面性；五元环和六元环的平面彼此扭转3.0 (1)°。在晶体中，弱的C—H⋯O氢键将通过在[010]方向上的平移相关的分子连接成链。
