Abstract

The mol-ecule of the title compound, C(18)H(10)O(4), is centrosymmetric and planar. A long phenolic O-H bond is observed [1.19 (9) Å], which is involved in an intra-molecular hydrogen bond between the phenolic and quinonoid O atoms. The mol-ecules pack in a herringbone pattern and are linked to each other via inter-molecular C-H⋯O hydrogen bonds (2.73-2.77 Å).

摘要

标题化合物C(18)H(10)O(4)的分子是中心对称且平面的。观察到一个较长的酚羟基O—H键[1.19 (9) Å]，它参与了酚羟基与醌型O原子之间的分子内氢键。分子以人字形模式堆积，并通过分子间C—H⋯O氢键(2.73 - 2.77 Å)相互连接。
