Abstract

In the crystal structure of the title compound, C19H18Cl2N2O4, N—H⋯O hydrogen bonds link the mol­ecules into infinite chains along the b axis. The structure also features weak C—H⋯O and C—H⋯Cl hydrogen bonds and C—H⋯π and (lone pair)⋯π inter­actions [Cl⋯centroid = 3.5871 (7) Å]. An intra­molecular N—H⋯O bond occurs.
