چکیده
In the title compound, C(17)H(12)O(4), the chromene unit is approximately planar, the maximum deviation from the mean plane being 0.0166 Å. The attached phenyl ring makes a dihedral angle of 53.2 (1)° with the fused ring system. The packing of the mol-ecules in the crystal structure is governed by C-H⋯O and O-H⋯O hydrogen-bonding inter-actions.
