摘要：

The title compound, also known as intricatinol, C17H14O5, is a homoisoflavanoid that was isolated for the first time from the twigs and stems of Caesalpinia digyna Rottler. The pyran ring is in an envelope form. O - H (. . .) O intramolecular hydrogen bonds are observed. Symmetry-related molecules are linked via O - H (. . .) O intermolecular interactions to form infinite one-dimensional chains. These chains are interconnected to form a three-dimensional molecular network.
