Abstract: The distinctive feature of the structure of the title compound, C₁₆H₁₀Cl₂O₂, is the formation of a zigzag chain along [100] via ClCl interactions [3.591 (1) and 3.631 (1) Å]. The chromanone moiety is fused with the benzene ring and adopts a half-chair conformation. The dihedral angle between the benzene ring of the chromanone moiety and the dichlorobenzene plane is 56.14 (8)°.
