Dibromido(6-methyl-2,2′-bipyridine-κ2 N,N′)cobalt(II)
نویسندگان
چکیده
In the mol-ecule of the title compound, [CoBr2(C11H10N2)], the Co(II) atom is four-coordinated in a distorted tetra-hedral geometry by two N atoms from a chelating 6-methyl-2,2'-bipyridine ligand and two terminal Br atoms. In the crystal, π-π stacking inter-actions between the pyridine rings along the a-axis direction [centroid-centroid distance = 3.761 (7) Å] and C-H⋯Br hydrogen bonds in the bc plane together generate the three-dimensional packing.
