In the title compound, [Co(NO3)2(C18H16N2O2)2]n, the CoII ion is located on an inversion center and is six-coordinated in an octahedral environment defined by four N atoms of the pyridine rings and two O atoms of the nitrate anions. The ligands link the CoII ions into a linear chain running along . One O atom of the nitrate ligand is disordered over two positions with site-occupancy factors of 0.59 (4) and 0.41 (4).
