Abstract

The electrochemistry of [CuL1] I and [CuL2] 2 [H2L1 = 1,2-bis(pyridine-2-carboxdmido)benzene, H2L2 = 3,4-bis(pyridine-2-carboxamido)toluene] was investigated. Both complexes show a quasi-reversible Cu(II/I) reduction near -1.6 V vs Fc(+)/Fc. Spectroelectrochemistry confirmed that the Cu(III) state is accessible near +0.4 V, and undergoes an EC reaction (k similar or equal to 10 s(-1)) to generate a new Cu(II) species.
