description The asymmetric unit of the title compound, C(17)H(14)O(4), contains two independent mol­ecules which differ in the relative orientations of the phenyl rings with repect to the essentially planar [maximum deviations of 0.029 (2) and 0.050 (2) Å in the two mol­ecules] chromene fused-ring system, forming dihedral angles of 10.3 (5) and 30.86 (5)° in the two mol­ecules. The crystal structure is stabilized by weak C—H⋯O and C—-H⋯π inter­actions, and π–π stacking inter­actions.
