10-Phenyl-6b,7,8,9,9a,10-hexahydro-6H-cyclopenta[4,5]pyrano[3,2-c]chromen-6,9-dione
In the title compound, C(21)H(16)O(4), the dihedral angle between the phenyl ring and the 2H-chromene ring system is 59.8 (2)°. The crystal packing is stabilized by weak π–π stacking interactions [centroid–centroid distances = 3.667 (2) Å] and intermolecular C—H⋯O hydrogen-bonding interactions....
