[Cu(2,9-dimethyl-1,10-phenanthroline)2]2+ and [Cu(6,6′-bipyridine)2]2+/+ complexes with no coordinated solvent molecule were synthesized and crystal structures were analyzed. Electrochemical measurement were carried out by using a BAS 100B/W electrochemical analyzer. The coordination geometry around the Cu(I) center was in the D2d symmetry while a D2 structure was observed for the four-coordinate Cu(II) complexes. The study revealed that the D2 structure of the Cu(I) complex retained in nitromethane, although a five-coordinate Thp species, was readily formed upon dissolution of the solid in acetonitrile.
