In the title mol-ecule, C16H12Cl2O2Se, the C-Se-C angle is 100.05 (14)°, with the dihedral angle between the planes of the benzene rings being 69.92 (17)°. The average endocyclic angles (Se-Car-Car; ar = aromatic) facing the Se atom are 120.0 (3) and 119.4 (3)°. The Se atom is essentially coplanar with the benzene rings, with Se-Car-Car-Car torsion angles of -179.2 (3) and -179.7 (3)°. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds forming chains propagating along the a-axis direction. The chains are linked via C-H⋯π inter-actions, forming a three-dimensional network.
在标题分子C₁₆H₁₂Cl₂O₂Se中，C-Se-C角为100.05 (14)°，苯环平面之间的二面角为69.92 (17)°。面向Se原子的平均环内角（Se-Car-Car；ar = 芳族）为120.0 (3)°和119.4 (3)°。Se原子基本与苯环共面，Se-Car-Car-Car扭转角为 -179.2 (3)°和 -179.7 (3)°。在晶体中，分子通过C-H⋯O氢键相连形成沿a轴方向传播的链。这些链通过C-H⋯π相互作用相连，形成三维网络。
