title: 6-(Hex-5-en-yloxy)naphthalene-2-carb-oxy-lic acid.
abstract: The asymmetric unit of the title compound, C17H18O3, comprises three independent mol-ecules with similar geometries. In each mol-ecule, the carbonyl group is twisted away from the napthalene ring system, making dihedral angles of 1.0 (2), 1.05 (19)° and 1.5 (2)°. The butene group in all three mol-ecules are disordered over two sets of sites, with a refined occupancy ratio of 0.664 (6):0.336 (6). In the crystal, mol-ecules are oriented with respect to their carbonyl groups, forming head-to-head dimers via O-H⋯O hydrogen bonds. Adjacent dimers are further inter-connected by C-H⋯O hydrogen bonds into chains along the a-axis direction. The crystal structure is further stabilized by weak C-H⋯π inter-actions.
