Nine copper(Ⅱ) oxyanion, and mixed oxyanion complexes that have four- or five-coordinate geometries around copper(Ⅱ) centers were derived from sparteine copper(Ⅱ) dinitrate precursor [Cu(C15H26N2)(NO3)2]. The precursor complex undergoes an anion exchange with various oxyanions, and an interchange reaction with other sparteine copper(Ⅱ) complexes. The [Cu(C15H26N2)(CH3CO2)2] also undergoes “halogen atom abstraction” reaction with CCl4 to produce the mixed anion complex [Cu(C15H26N2)(CH3CO2)Cl]. The whole set of prepared complexes has been used for the comparative electrochemical and spectroscopic studies.
