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.
标题化合物C₁₈H₁₆O₂结晶于中心对称空间群P2(1)/a中。单一类型的羧基氢键围绕对称中心形成环状二聚体。羧基H原子与羧基O原子一样有序排列。该结构由呈人字形排列的芳香环双层组成，双层之间由氢键连接的脂肪链双层隔开，它与4-(2-萘基)丁酸及其他末端芳基取代的正脂肪族羧酸的结构非常相似。
