In the title compound, C19H10ClNO4, the dihedral angle between the naphtho-quinone and coumarin rings is 48.99 (6)°. In the crystal, mol-ecules are linked by strong N-H⋯O hydrogen bonds into chains with graph-set motif C(6) along [101]. The packing also features π-π stacking inter-actions between naphtho-quinone and coumarin rings [centroid-to-centroid distances = 3.7679 (12) and 3.6180 (13) Å]. ...[more]
