Abstract

The title compound, C16H14O6, was recrystallized under solvothermal conditions. The mol-ecules are located on inversion centres, with one complete mol-ecule generated from the asymmetric unit by inversion. There are intra-molecular O-H⋯O hydrogen bonds involving the carb-oxy-lic acid group and the O atom of the adjacent meth-oxy group. In the crystal, mol-ecules are linked via O-H⋯O hydrogen bonds, forming chains propagating along [100]. The chains are linked via C-H⋯O hydrogen bonds, forming sheets parallel to (001).
