The Study of Electrochemical Behavior of Mono and Dinuclear Co(III) Complexes, trans-[pyCo((DO)(DOH)pn)(L)]PF6 and [{pyCo((DO)(DOH)pn)}2((mu)-dicyd)](PF6)2

Electrochemical behavior of the new mono and dinuclear Co (III) complexes of the types trans-fpyCo((DO)(DOH)pn )(L)]PF6 and [{py Co((DO)(DOH)pn)}2 ((mu)-dicyd)] (PF6)2 have been studied in acetonitrile solution. All the mono nuclear complexes show two quasi- reversible reduction couples associate to Co(III/II)and Co(II/I). Each of these redox couples split to two one electron waves in dinuclear complex.
