Abstract
In the title compound, C(10)H(8)ClNO(2), the dihedral angle between the aromatic benzene ring and the imide segment is 69.5 (1)°. In the crystal structure, mol-ecules are linked by very weak C-H⋯π inter-actions along the [001] direction.Entities:

| Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
