In the title compound, C19H16BrClO4, both the fused xanthene rings and one of the cyclohexane rings adopt envelope conformations, while the other cyclohexane ring is in a chair conformation. In the crystal, molecules are linked by C—H
O hydrogen bonds, forming infinite chains running along [10-1] incorporating R22(16) ring motifs. In addition, C—Hπ interactions and weak π–π stacking interactions [centroid–centroid distance = 3.768 (3) Å] help to consolidate the packing.
