The title compound, C(14)H(12)N(2)O(2), is almost planar with an r.m.s. deviation for all non-H atoms of 0.038 Å. The observed planarity is rationalized in terms of a close intra-molecular C-H⋯O inter-action. Supra-molecular layers, two mol-ecules thick and with a step topology, are formed in the crystal packing via C-H⋯O contacts involving the carbonyl O atom, which accepts two such bonds, and π-π inter-actions between the components of the fused ring system and the phenyl ring of inversion-related mol-ecules [centroid-centroid distances = 3.6819 (13) and 3.6759 (12) Å].
标题化合物C(14)H(12)N(2)O(2)几乎呈平面状，所有非氢原子的均方根偏差为0.038 Å。观察到的平面性可通过紧密的分子内C-H⋯O相互作用来解释。在晶体堆积中，通过涉及羰基O原子（该原子接受两个此类键）的C-H⋯O接触以及稠环系统的组分与反演相关分子的苯环之间的π-π相互作用[质心-质心距离 = 3.6819 (13) 和3.6759 (12) Å]，形成了两层分子厚且具有阶梯拓扑结构的超分子层。
