摘要：

In the crystal structure of the title compound, C13H8O4, the inversely oriented molecules form inversion dimers through pairs of O-H center dot center dot center dot O hydrogen-bonding interactions. An intramolecular O-H center dot center dot center dot O hydrogen bond occurs. In the packing of the molecules, the nearly planar 2-(furan-2-yl)-4H-chromene units [dihedral angle between the chromene and furan rings = 3.8 (1)degrees] are either parallel or inclined at an angle of 80.7 (1)degrees
