A. J. Kresge, A. J. Lough and Y. Zhu

Abstract: There are four independent molecules in the asymmetric unit of the title compound, C₇H₁₀O₃, and two of the molecules are disordered. Molecules form two independent O-HO hydrogen-bonded dimers, through the carboxyl groups, with OO distances of 2.669  (3), 2.661  (3), 2.653  (3) and 2.654  (3)  Å. Each hydrogen-bonded dimer contains a disordered molecule.
