1,3,5-Tris(bromomethyl)benzene

The asymmetric unit of the title compound, C₉H₉Br₃, is composed of a single molecule. Two bromo substituents are located on one side of the plane of the aromatic ring and the third is on the opposite side, with the molecular unit exhibiting an approximate noncrystallographic C_s point group. The crystal structure is rich in Br...Br, CH₂...Br and CH...π weak intermolecular contacts which mediate the crystal packing of individual molecules. These interactions promote a red-shift of a handful of vibrational modes (associated with the pendant –CH₂Br groups) compared with values from theoretical density functional theory (DFT) calculations.
