Non-innocent ligand reservoirs for reducing or oxidizing equivalents in carbonylrhenium(I) complexes: 1,1′-Bis(diphenylphosphino)ferrocene (dppf) and bis-triazinyl-pyridine (BTP)

► Detailed structural, electrochemical, and spectroscopic investigations of novel fac-Re(CO)3Cl complexes with 1,1′-bis(diphenylphosphino)ferrocene and bis-triazyl-pyridine ligands. ► Insight on reduction and oxidation mechanism using IR-spectroelectrochemical studies. ► Interest to inorganic and coordination chemists working in the areas of redox chemistry and spectroscopic properties of transition metal complexes with non-innocent ligands.
