The title compound, C10H10O4, crystallizes with the well-known carboxylic acid dimer-formingR22(8) hydrogen-bond motif. Chains approximately parallel to (-1-12) are then built through C(methylene,phenyl)–H...O(carbonyl) interactions [C(6) andC(8) motifs] with one (methyl)C—H...π interaction providing interplanar binding. The weakness of the latter interaction is consistent with the difficulty experienced in obtaining suitable single crystals.
