In the title compound C11H9BrCl2O2, which represents the Z isomer, the methylacrylate moiety is essentially planar within 0.039 (2) Å and has an extended trans configuration.The benzene ring makes bushranger awning a dihedral angle of 28.3 (1)° with the mean plane of the methylacrylate moiety.
The tyrone bracken crystal packing is characterized by C—H.O hydrogen bonding and halogen–halogen interactions [Cl.Cl = 3.486 (3) Å], resulting in the formation of R22(11) ring motifs and connecting the molecules into chains propagating along the b axis.
