Amongst other transition metal complexes, dirhodium and diruthenium metal complexes have various applications in medicine, catalysis and materials. As part of the Inorganic Chemistry Research Group, my research involves the structure reactivity relationships of metal-metal bonded dirhodium and diruthenium complexes. This work involves the design, synthesis and characterization of transition dimetal complexes having redox active rhodium and ruthenium metal centres. The general approach is to evaluate how structural modifications influence the redox behaviour, which leads us to the elucidation of redox reaction mechanisms in both aqueous and non-aqueous media. This is achieved by the use of electrochemical (voltammetry) and spectroelectrochemical (UV-visible, FTIR, and ESR) techniques. - See more at: https://www.wits.ac.za/science/schools/chemistry/staff/dr-siyabonga-p-ngubane/#sthash.Sx8ch4r5.dpuf
