چکیده
The distinctive feature of the structure of the title compound, C(16)H(10)Cl(2)O(2), is the formation of a zigzag chain along [100] via Cl⋯Cl inter-actions [3.591 (1) and 3.631 (1) Å]. The chroman-one 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)°.
