The title compound, C 8 H 7 Br 3 , possesses normal geometrical parameters. There are two independent molecules; one shows whole‐molecule disorder with respect to an inversion‐symmetry‐generated partner, while the other is undisordered. This results in the unusual situation of Z ′ = 1.5 and Z = 6 for a monoclinic crystal system. The undisordered molecule interacts with its neighbours by way of π–π stacking.
