The crystal structure, Hirshfeld surface analysis and energy frameworks of 2-[2-(meth­oxy­carbon­yl)-3,6-bis­(meth­oxy­meth­oxy)phen­yl]acetic acid

In the title compound, C(14)H(18)O(8), (I), the meth­oxy­carbonyl [–C(=O)OCH(3)] and the acetic acid [–CH(2)C(=O)OH] groups are inclined to the benzene ring by 79.24 (11) and 76.71 (13)°, respectively, and are normal to each other with a dihedral angle of 90.00 (13)°. In the crystal, mol­ecules are linked by a pair of O—H⋯O hydrogen bonds forming the familiar acetic acid inversion dimer. The dimers are linked by two C—H⋯O hydrogen bonds and an offset π–π inter­action [inter­centroid distance = 3.6405 (14) Å], forming layers lying parallel to the (10[Image: see text]) plane. The layers are linked by a third C—H⋯O hydrogen bond and a C—H⋯π inter­action to form a supra­molecular framework.
