Abstract
The title compound, C(14)H(12)O(3), is an α-hy-droxy-carb-oxy-lic acid whose ortho-rhom-bic polymorph has been reported earlier [Qiu et al. (2007 ▸). Inorg. Chim. Acta, 360, 1819-1824]. The asymmetric unit contains two complete mol-ecules. Classical hydrogen bonds, as well as C-H⋯O contacts, connect the mol-ecules to infinite chains along the crystallographic c-axis direction.
