title: 3-Acet-oxy-2-naphthoic acid.
abstract: In the title compound, C(13)H(10)O(4), an analog of acetyl-salicylic acid, the naphthalene unit is twisted slightly due to ortho disubstitution [dihedral angle between conjugated rings system in the naphthalene unit = 2.0 (2)°]. The mean planes of the carb-oxy-lic and ester groups are almost coplanar and perpendicular, respectively, to the mean plane of the conjugated aromatic system, making dihedral angles of 8.9 (3) and 89.3 (1)°. In the crystal, mol-ecules are paired through their carb-oxy-lic groups by the typical centrosymmetric O-H⋯O inter-actions with R(2) (2)(8) hydrogen-bond motifs. In addition, several weak C-H⋯O inter-molecular contacts are also observed. Finally, the mol-ecules are stacked along crystallographic [100] and [010] directions.
