Dibromido(6,6'-dimethyl-2,2'-bipyridine-?(2)N,N')cobalt(II).

ABSTRACT: In the title compound, [CoBr(2)(C(12)H(12)N(2))], the Co(II) atom is four-coordinated in a distorted tetra-hedral geometry by two N atoms from a 6,6'-dimethyl-2,2'-bipyridine ligand and by two terminal Br atoms. Inter-molecular C-H?Br hydrogen bonds and ?-? stacking between the pyridine rings in the bc plane [centroid-centroid distance = 3.725?(3)?Å] are present in the crystal structure.
