The title mol-ecule, C(14)H(10)Cl(4)Se, features a selenide bridge between two dichloro-benzyl units. The dihedral angle between the two benzene rings is 107.9 (16)°. In the crystal, weak π-π face-to-face aromatic inter-actions are observed [centroid-centroid distance between two adjacent (but crystallographically different) phenyl rings = 3.885 (5) Å], providing some packing stability. Short Cl⋯Cl contacts of 3.41 (2) Å are observed.
