The copper(II) Schiff base complexes linked to viologen via number 3 and 4 of methylene groups were synthesized and characterized. The complexes are the binuclear type, the second Cu(II) of which binds with two iodide ions to the phenolate edge of <I>N</I>,<I>N</I>′-bis(salicylidene)ethylenediaminatocopper(II). A pulse radiolytic study in acetonitrile showed that the intramolecular electron transfer from the viologen radical to the Cu(II)O<SUB>2</SUB>I<SUB>2</SUB> site occurred along with an intermolecular electron transfer between the viologen radical and the Cu(II)O<SUB>2</SUB>I<SUB>2</SUB> site of the other complexes existing in excess; also, the number of the methylene groups (3 and 4) little affected the intra- and intermolecular electron-transfer rate. A trinuclear copper(II) Schiff base complex linked to viologen via number 5 of methylene groups was also synthesized and characterized.
