The Study of Electrochemical Behavior of Mono and Dinuclear Co(Ⅲ) Complexes, trans-[pyCo((DO)(DOH)pn)(L)]PF_6 and [{pyCo((DO)(DOH)pn)}_2(μ-dicyd)](PF_6)_2

摘要

Electrochemical behavior of the new mono and dinuclear Co (Ⅲ) complexes of the types trans-[pyCo((DO)(DOH)pn )(L)]PF_6 and [{py Co((DO)(DOH)pn)}_2 (μ-dicyd)] (PF_6)_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.
