4-Hy­droxy-3-[(4-hy­droxy-6,7-dimethyl-2-oxo-2H-chromen-3-yl)(4-oxo-4H-chromen-3-yl)meth­yl]-6,7-dimethyl-2H-chromen-2-one

In the title compound, C(32)H(24)O(8), the mol­ecular structure is disordered over two positions with refined site occupancies of 0.8746 (10) and 0.1254 (10). The mean plane of the three chromeno rings make dihedral angles with each other of 65.12 (4), 62.91 (4) and 59.70 (4)° in the major occupancy...

Sumario:In the title compound, C(32)H(24)O(8), the mol­ecular structure is disordered over two positions with refined site occupancies of 0.8746 (10) and 0.1254 (10). The mean plane of the three chromeno rings make dihedral angles with each other of 65.12 (4), 62.91 (4) and 59.70 (4)° in the major occupancy component and 59.1 (3), 66.1 (3) and 58.8 (3)° in the minor component. Intra­molecular O—H⋯O hydrogen bonds stabil­ize the mol­ecular structure and the crystal structure is stabilized by weak C–H⋯π and π–π inter­actions [centroid–centroid distances 3.496 (6)–3.672 (7) Å].
