title: Bis(2,2'-bipyridine-κN,N')(nitrato-κO)copper(II) perchlorate.
abstract: In the title compound, [Cu(NO(3))(C(10)H(8)N(2))(2)]ClO(4), the five-coordinated Cu(II) atom has a distorted square-pyramidal CuN(4)O environment; the O atom is in the axial position whereas the N atoms from two bipyridine (bipy) ligands are in the equatorial plane. In the crystal, mol-ecules are assembled by C-H⋯O hydrogen bonding and π-π inter-actions between bipy groups [centroid-centroid distances = 3.7686 (16) and 3.7002 (16) Å] into a three-dimensional network. The nitrite anion is equally disordered over two sets of sites.
