چکیده
In the title compound, C17H14O5, the dimeth-oxy-substituted benzene ring is twisted relative to the 4H-chromenon skeleton (r.m.s. deviation = 0.015 Å) by 5.2 (4)°. The C atoms of the meth-oxy groups lie close to the plane of their attached benzene ring [deviations = 0.036 (3) and 0.290 (3)Å for the meta and para substituents, respectively]. An intra-molecular O-H⋯O hydrogen bond closes an S(5) ring. In the cystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(10) loops and C-H⋯O inter-actions connect the dimers into [010] chains.
