resulted in the formation of the major chelated complex Fe2(μ-pdt)(CO)4κ2-Ph2PN(C6H4Me-p)PPh2} (3) concomitant with the minor complex 2. All the complexes 1-3 have been well characterized by elemental analysis, FTIR, NMR (1H, 31P) spectroscopies, and X-ray crystallography. Additionally, the electrochemical and electrocatalytic properties of complexes 1-3 are studied using cyclic voltammetry, where
