ankle-and-wrist-cuffs In the title compound, C16H11BrO3, the molecules adopt an E configuration with respect to the C=C double bond of the propenone unit.The 13 non-H atoms of the benzodioxole and propenone units are approximately coplanar (r.m.s.deviation = 0.
027 Å) and the bromobenzene ring plane forms SCOOP a dihedral angle of 10.8 (1)° to this plane.The structure is layered, with the molecules forming a herring-bone arrangement within each layer.
