In the title compound, C(16)H(14)O(4)·H(2)O, the dihedral angle betwen the benzene rings is 71.4 (6)°. The pyran ring is in a sofa conformation. In the crystal, O-H⋯O hydrogen bonds connect the components into a two-dimensional network parallel to (010), incorporating C(2) (2)(4) and C(2) (2)(11) chains. In addition, weak C-H⋯O, C-H⋯π and π-π stacking inter-actions [centroid-centroid distance = 3.768 (2) Å] are present.
在标题化合物C₁₆H₁₄O₄·H₂O中，苯环之间的二面角为71.4 (6)°。吡喃环呈沙发构象。在晶体中，O—H⋯O氢键将各组分连接成平行于(010)的二维网络，其中包含C₂(2)(4)和C₂(2)(11)链。此外，还存在弱的C—H⋯O、C—H⋯π和π—π堆积相互作用[质心-质心距离 = 3.768 (2) Å]。
