4-(3-phenanthryl)butanoic acid.
The title compound, C18H16O2, crystallized in the centrosymmetric space group P2(1)/a. The single type of carboxylic hydrogen bond forms cyclic dimers about centers of symmetry. The carboxylic H atom is ordered as are the carboxylic O atoms. This structure comprises double layers of aromatic rings in a herring-bone array separated by double layers of hydrogen-bonded aliphatic strings and is a very close analog of the structures of 4-(2-naphthyl)butanoic acid and other terminally arylsubstituted n-aliphatic carboxylic acids.
