The title compound crystallizes in the monoclinic space group P21/c with unit cell parameters a = 15.6239(15) Å, b = 14.0537(14) Å, c = 5.8396(5) Å, β = 92.666(3)°, V = 1280.8 (2) Å3, and Z = 4. The final reliability index is 0.0538 for 2921 observed reflections. Two phenyl rings of the title molecule are not coplanar, with a dihedral angle of 46.3(0)°. The molecular planarity of this substituted chalcone is strongly affected by the 4′-bromo group. The crystal cohesion is accentuated by π···π, C–H···Br interactions and R3 1 (11) hydrogen bond.
