ABSTRACT: In the title compound, C12H10Cl2N2O2, the seven-membered heterocycle displays a half-chair conformation. The mean plane through the oxo-propyl-idene group makes a dihedral angle of 36.44 (9)° with the fused benzene ring. An intra-molecular N-H⋯O hydrogen bond to close an S(6) loop is noted. An important feature of the mol-ecular packing are N-H⋯O hydrogen bonds that lead to the formation of helical supra-molecular chains along the b axis.
