The title compound, C12H10ClNO3, the indoline ring system is essentially planar, with a maximum deviation of 0.009 Å for the N atom. The indoline ring and acetate group are essentially coplanar, with a maximum deviation of 0.086 Å for the O atom. The mean plane through the methoxy-carbonyl-methyl group forms a dihedral angle of 3.68 (5)° with the plane of the indoline ring system. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen-bond inter-action. In the crystal, π-π stacking inter-actions [centroid-centroid distance = 3.7677 (8) Å] occur between benzene rings, forming a chain running along the c-axis direction.
标题化合物C₁₂H₁₀ClNO₃中，二氢吲哚环系基本呈平面状，N原子的最大偏差为0.009 Å。二氢吲哚环和乙酸酯基团基本共面，O原子的最大偏差为0.086 Å。穿过甲氧基羰基甲基的平均平面与二氢吲哚环系平面形成3.68 (5)°的二面角。分子结构通过分子内C—H⋯O氢键相互作用得以稳定。在晶体中，苯环之间发生π-π堆积相互作用[质心-质心距离 = 3.7677 (8) Å]，形成沿c轴方向延伸的链。
