Abstract

In the title complex, [Cu(NO3)2(C10H8N2)], the Cu(II) cation is chelated by two nitrate anions and by one 2,2'-bi-pyridine ligand in a distorted N2O4 octa-hedral geometry. The dihedral angle between the pyridine rings is 1.92 (11)°. In the crystal, π-π stacking between parallel pyridine rings of adjacent complex mol-ecules is observed, the centroid-centroid distance being 3.6788 (19) Å. Weak C-H⋯O hydrogen bonds further link the mol-ecules into a three-dimensional supra-molecular architecture.
