The title compound, C(11)H(17)Br, has crystallographically imposed mirror symmetry in the solid state with mol-ecules bis-ected by mirror planes parallel to the crystallographic ac plane (five C atoms, three H atoms and the Br atom lie on the mirror plane). The asymmetric unit contains one half-mol-ecule. The crystal packing is stabilized only via weak non-specific van der Waals inter-actions.
