Axial Coordination Effects of Pyridine on the Electrochemistry of (TPP)Co in 1,2-Dichloroethane Solution

摘要

The electrochemistry of (TPP)Co in the presence of pyridine was investigated indichloroethane solution by cyclic voltammetry. With the addition of pyridine to the solution, thereduction Peaks of the axial complex compounds, (TPP)Co(III)(Py) and (TPP)Co(III)(Py)2 wereobserved. It was found that the reduchon peak of Co(II)/Co(I) shifted to about -1 .20V (SCE) with theincrease of added Pyridine. The new reduction peak may be attributed to the direct reduction of theaxially complex (TPP)Co(II)(Py)
