Abstract

In the title compound, [CoBr2(C12H12N2)], the CoII atom is four-coordinated in a distorted tetra­hedral geometry by two N atoms from a 6,6′-dimethyl-2,2′-bipyridine ligand and by two terminal Br atoms. Inter­molecular C—H⋯Br hydrogen bonds and π–π stacking between the pyridine rings in the bc plane [centroid–centroid distance = 3.725 (3) Å] are present in the crystal structure.
