(2,2′-Bipyridine-κ2N,N′)bis(nitrato-κ2O,O′)copper(II)

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, π–π 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.
