In the title compound, C10H8O2, the four symmetry-related molecules are connected to each other through O—H…O hydrogen bonds to form a helical chain along the b axis. The interconnected system is further extended along the c axis through O—H…O hydrogen bonds to form a two-dimensional network. Unlike its trans isomer, no C—H…O or C—H… interactions are observed in the crystal structure.
