Resumo: | Bis-(µ2-oxo)-tetrakis{[1-feniltriazeno-1,3-diil)-2-(feniltriazenil)benzeno cobre(II) é um complexo tetranuclear que apresenta quatro íons Cu(II) coordenados por quatro ligantes 1,2-bis(feniltriazeno)benzeno em ponte, com uma cadeia diazoamínica desprotonada, e dois ligantes O2-. O complexo apresenta um processo de redução por dois elétrons a E1/2 = -0,95 V vs Fc+/Fc. Voltametria cíclica e espectroeletroquímica demonstraram um processo reversível. Quando imobilizado em eletrodo de pasta de carbono, o complexo eletrocatalisa a redução de O2 dissolvido em solução aquosa a –0,3 V vs SCE. A corrente obtida apresenta linearidade com a concentração de O2._________________________________________________________________________________________ ABSTRACT: Bis-(µ2-oxo)-tetrakis{[1-feniltriazene-1,3-diil)-2-(phenyltriazenil)benzene copper(II) is a tetranuclear complex which shows four Cu(II) ions coordinated by four 1,2-bis(phenyltriazene)benzene bridged ligands, with one diazoaminic deprotonated chain, and two O2- ligands. The complex reduces at E1/2 = -0.95 V vs Fc+/Fc, a two electrons process. Cyclic voltammetric and spectroelectrochemical studies showed a reversible process. When immobilized on carbon paste electrode, the complex electrocatalyses the reduction of O2 dissolved on aqueous solution at –0.3 V vs SCE potential. The obtained current shows linearity with O2 concentration. |
