IUCrData, 2020 Apart from the OH group, the molecule of the title compound, C11H10O, is almost planar with all carbon atoms located within 0.03 Å of their mean plane. In the crystal, the molecules are linked by O—H...O hydrogen bonds, generating infinite chains running parallel to the [100] direction.

1-(Phenylsulfonyl)naphthalene [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 In the title compound, C16H12O2S, the phenyl ring is nearly perpendicular to the naphthalene system [dihedral angle = 80.3 (1)°]. The packing is consolidated by a weak C—H...π interaction involving neighbouring naphthalene and benzene rings. In addition, there exist two different offset π–π stacking interactions between benzene rings and between ...
