RESUMO
In the title compound, C19H10ClNO4, the dihedral angle between the naphtho-quinone and coumarin rings is 48.99â (6)°. In the crystal, mol-ecules are linked by strong N-Hâ¯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 = 3.7679â (12) and 3.6180â (13)â Å].
