Inter-actions of the π-π type are absent between cations in the stacks [centroid-centroid separation = 5.01 (5) Å]. Significant inter-molecular Br-aryl inter-actions are present in the structure, especially an unusually short Br-ring centroid inter-action of 3.78 (1) Å. The coordination geometry of the anion is approximately tetrahedral and a twofold rotation axis passes through the Co atom.Acta crystallographica.
