The title compound, C(18)H(18)Br(2)N(2), is centrosymmetric with the mid-point of the central C-C bond of the butyl group located on an inversion center. The terminal benzene ring is approximately perpendicular to the central butyl plane [dihedral angle = 71.9 (8)°]. No hydrogen bonding or aromatic stacking is observed in the crystal.

The title compound, C(20)H(23)BrN(2)O(2), containing an ibuprofen core, crystallizes with three independent mol-ecules of similar conformation in the asymmetric unit. In these three mol-ecules, the two benzene rings make dihedral angles of 82.7 (2), 71.2 (2) and 78.0 (3)° with respect to each other. The atoms of the isobutyl groups in two of the mol-ecules are disordered over two positions, wit...
