The asymmetric unit of the title compound, C26H12ClNO6, consists of two independent mol­ecules. The central pyran rings and both the 1-benzopyran ring systems are nearly planar in both mol­ecules [r.m.s. deviations of pyan rings = 0.0264 (1) and 0.0326 (1) Å for molecules A and B, respectively; r.m.s. deviations of benzopyran rings = 0.0439 (1) and 0.0105 (1) for molecule A, 0.0146 (1) and 0.0262 (1) Å for molecule B]. In the crystal, the molecules are linked by C—H...O, N—H...O and C—H...π inter­actions.
