The title complex, [Co(N-3)(3)(C10H8N2)(C5H5N)], adopts fac-octahedral
coordination geometry. All the azido ligands are terminally coordinat
ed with an average Co-N-N angle of 125 degrees. The pyridine Ligand is
least strongly coordinated to the Co-III atom and forms the longest C
o-N bond [1.992(2) Angstrom]. The bipyridine rings lie in the equatori
al plane and are nearly perpendicular to the pyridine ring.
