Abstract: In the title complex, [Cu(NO3)2(C10H8N2)], the CuII cation is chelated by two nitrate anions and by one 2,2'-bi­pyridine ligand in a distorted N2O4 octa­hedral geometry. The dihedral angle between the pyridine rings is 1.92 (11)°. In the crystal, [pi]-[pi] stacking between parallel pyridine rings of adjacent complex mol­ecules is observed, the centroid-centroid distance being 3.6788 (19) Å. Weak C-H...O hydrogen bonds further link the mol­ecules into a three-dimensional supra­molecular architecture.
