The crystal structure of the title compound, C(9)H(10)O(4), was first reported by Swaminathan, Vimala & Lotter [Acta Cryst. (1976), B32, 1897-1900]. It has been re-examined, improving the precision of the derived geometric parameters. The asymmetric unit comprises a non-planar independent mol-ecule, as the meth-oxy substituents force the carb-oxy group to be twisted away from the plane of the aromatic ring by 56.12 (9)°. Due to the anti-planar conformation adopted by the OH group, the mol-ecular ...[more]
