2,4-Dichloro-N-(2,5-dioxopyrrolidin-1-yl)benzamide

Abstract

In the title compound, C11H8Cl2N2O3, the plane of the pyrrolidine ring (r.m.s. deviation = 0.065 Å) makes a dihedral angle of 52.9 (2)° with the plane of the benzene ring. The least-squares plane of the central amide fragment makes dihedral angles of 49.3 (7) and 77.9 (7)° with those of the benzene and pyrrolidine rings, respectively. In the crystal, molecules are linked via N—H...O hydrogen bonds, forming chains along the b-axis direction. π–π interactions link these chains into a two-dimensional network parallel to (100).
