The title compound, [Cu(ONO)(C12H12N2)2]ClO4.0.5 CH3CN, was prepared as an air –stable green solid by the addition of NaNO2 to an acetonitrile solution of Cu(4,4’- dimethyl-2,2’-bipy)2(ClO4)2 at room temperature and was characterized by elemental analysis, IR and single –crystal X-ray diffraction. There are two anions and two cations in the asymmetric unit but only one acetonitrile solvent molecule. The geometry around each central copper(II) ion is distorted octahedral with significant Jahn-Teller distortion. Each copper is coordinated to two bidentate 4,4’- dimethyl-2,2’-bipyridine molecules and asymmetrically to a bidentate nitrile anion with one short and one long Cu – O bond. Intermolecular C – H ….O and π…. π interactions assist in the crystal packing.

Bis(4,4’- dimethyl-2,2’-bipyridine –k2 N,N’) (nitrito- kO) copper(II) perchlorate hemi-acetonitrile solvate
