The title compound, C16H10Cl2O3, is almost planar with a dihedral angle of 0.14 (16)° between the benzodioxole ring system and the di­chloro­benzene ring that are bridged by the olefinic double bond. The corresponding value reported for the monoclinic polymorph is [5.57 (9)° (Lokeshwari et al. (2017[Lokeshwari, D. M., Pavithra, G., Renuka, N., Lokanath, N. K., Naveen, S. & Ajay Kumar, K. (2017). IUCrData, 2, x170103.]). IUCrData, 2, x170103). The carbonyl group lies almost in the plane of the olefinic double bond and is twisted slightly from the benzodioxole ring plane. In the crystal, the mol­ecules are linked by weak C—H⋯O and C—H⋯Cl hydrogen bonds, forming a chain propagating along the b-axis direction.
