    • Abstract

       

      The redox activity of four oximato-bridged strongly exchange-coupled copper(II) dimers is examined using cyclic voltammetry and coulometry in acetonitrile solution. A well-defined quasi-reversible couple corresponding to the process Cu2II+ e⇌ CuIICuI is observed in all cases. The couple corresponding to the next stage of reduction CuII CuII + e ⇌Cu2I is identified in two complexes. TheE2980 values for the various couples are reported with rationalisation of observed trends in terms of exchange interaction and ligand 10 Dq. The circumstances which may lead to superposition of the two successive one electron couples in copper(II) dimers are discussed.
