In the title mol-ecule, C(14)H(10)O(4)Se, the dihedral angle between the two benzene rings is 74.6 (1)°. Both hy-droxy-benzaldehyde groups form intra-molecular O-H⋯O hydrogen bonds. In the crystal, pairs of mol-ecules are linked by pairs of weak C-H⋯π(arene) inter-actions, forming centrosymmetric dimers. In addition, mol-ecules are linked by π-π stacking inter-actions, with a centroid-centroid distance of 3.785 (2) Å, forming chains along the c axis.
在标题分子C₁₄H₁₀O₄Se中,两个苯环之间的二面角为74.6 (1)°。两个羟基苯甲醛基团均形成分子内O-H⋯O氢键。在晶体中,分子对通过成对的弱C-H⋯π(芳烃)相互作用相连,形成中心对称二聚体。此外,分子通过π-π堆积相互作用相连,质心间距为3.785 (2) Å,沿c轴形成链状结构。
