In the title molecule, 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—Cartorsion angles of −179.2 (3) and −179.7 (3)°. In the crystal, molecules are linkedviaC—H...O hydrogen bonds forming chains propagating along thea-axis direction. The chains are linkedviaC—H...π interactions, forming a three-dimensional network.
