Abstract
In the title compound, C10H10Cl2N2O2, the secondary amide groups are differently twisted relative to the benzene ring, with dihedral angles between the respective planes of 21.03 (2) and 81.22 (2)°. In the crystal, the molecules are connected by N—H⋯O and C—H⋯O hydrogen bonds, forming a two-dimensional polymeric network parallel to (001). One of the amide carbonyl O atoms accepts two H atoms in N—H⋯O and C—H⋯O interactions, forming an R 2 2(6) ring motif.
