Abstract

In the title compound, C(11)H(9)NO(3), the dihedral angle between the meth-oxy-benzene and 1H-pyrrole-2,5-dione rings is 75.60 (10)°. The C atom of the meth-oxy group is close to coplanar with its attached ring [deviation = 0.208 (2) Å]. In the crystal, weak aromatic π-π stacking [centroid-centroid separation = 3.8563 (13) Å] occurs between inversion-related pairs of benzene rings.

摘要

在标题化合物C₁₁H₉NO₃中，甲氧基苯环与1H - 吡咯 - 2,5 - 二酮环之间的二面角为75.60（10）°。甲氧基的C原子与其相连的环接近共平面[偏差 = 0.208（2）Å]。在晶体中，苯环的反演相关对之间发生弱的芳香π - π堆积[质心 - 质心间距 = 3.8563（13）Å]。
