They exhibit two sequential irreversible reductions assigned to the MIII → MII and MII → MI reductions, which are dependent on the methylation of the bis(pyrazolyl)alkane ligands.engBis(pyrazolyl)alkaneRhodium(III) and Iridium(III) ComplexesCyclic VoltammetryControlled Potential ElectrolysisElectrochemical properties of (H5-C5Me5)-rhodium and – iridium complexes Bis(pyrazolyl)alkane ligandsjournal article10.4152/pea.201404253
