The structure of 3-bromo-7-(dimethylamino)-4-methylcoumarin (1) was determined by X-ray crystallography. It crystallizes in the space group P21/n (#14) with cell parameters a = 9.000(3)Å, b = 11.561(3)Å, c = 10.591(3)Å, β = 96.5568(14)°, Z = 4, and V = 1094.8(5)Å3. The molecule is almost planar. Intermolecular C=O…Br, C-H…O, C-H…π, and π…π interactions were observed in the crystal lattice.
