2-Bromo-1,3-bis(bromomethyl)benzene, with Z' = 1.5: whole-molecule disorder of one of the two independent molecules.
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 pi-pi stacking.
