Abstract
The structure of the title compound, C(18)H(22)O(2), contains two non-equivalent molecules which differ primarily in the location of the -OH groups on opposite sides or on the same side of the molecular plane. Inversion-symmetric pairs of molecules form intermolecular O-H...O hydrogen-bonded tetrameric synthons that link non-equivalent molecules into an approximately square double layer parallel to (-102). Recently reported fluorinated analogues [Kane, Meyers, Yu, Gerken & Etzkorn (2011). Eur. J. Org. Chem. pp. 2969-2980] have significantly different structures of varying complexity that incorporate intramolecular hydrogen bonding and suggest that further study of structure versus substituents in vicinal dialkynols could be fruitful.
