title: 5,6,7,8-Tetra-hydro-naphthalene-1-carboxylic acid.
abstract: In the mol-ecule of the title compound, C(11)H(12)O(2), the cyclo-hexane ring adopts a half-chair conformation. In the crystal structure, mol-ecules are linked into centrosymmetric dimers by pairs of O-H⋯O hydrogen bonds, and the dimers are linked together by π-π inter-actions [centroid-centroid distance = 3.8310 (13) Å] and C-H⋯O bonds.
