2,3-Dihydro-1H-cyclopenta[b]naphthalen-1-ol

Abstract

In the title compound, C 13H 12O, the cyclo-pentene ring fused with the naphthalene group adopts an envelope conformation. The cyclo-pentene torsion angle, with the fusion bond at the centre, has a magnitude of 1.16 (16)°. In the crystal, neigh-bouring molecules are connected through O - H⋯O hydrogen bonds into an R 44(8) ring motif. The crystal packing also features weak π-π stacking interactions [centroid-centroid distance = 3.8981 (8) Å] and C - H⋯π interactions.
