Abstract:In the title compound, C15H9Cl2N3O, an intramolecular C—H⋯O interaction generates an S(7) ring motif. The cyclopenta-1,3-diene ring forms dihedral angles of 1.93 (6) and 2.78 (6)° with its attached benzene rings. In the crystal, molecules are linked by C—H⋯N and C—H⋯O hydrogen bonds, thereby forming layers lying parallel to the ac plane. The crystal also features a π–π interaction with a centroid–centroid distance of 3.5612 (6) Å.
