Abstract
In this paper, the electrochemical oxidation of three Pt(II) complexes containing pyrrole oxime (HL)
having a general formula of [Pt(NH3)Cl(L)] (1), [Pt(L)2] (2), and K[PtCl2(L)] (3) has been investigated by
in-situ spectroelectrochemistry in dimethylformamide (DMF). An irreversible metal-based oxidation
process occurs during the anodic scan for each of the three complexes. The electronic absorption spectral
changes indicate that all the three complexes generate similar Pt(IV) compounds and free ligand. Our
experimental data is supported by quantum chemistry calculations utilizing density functional theory. In
addition, the frontier orbital energy distributions indicate that electron densities are localized on mainly
platinum atom.
