Electrochemical and spectroelectrochemical (UV–Vis, IR, EPR) of pd (pd= 1, 10-
phenanthroline-5, 6-dione), Pt (N, N′-pd) Cl2, Pd (N, N′-pd) Cl2,[Ru (bpy) 2 (N, N′-pd)]
Cl2 (bpy= 2, 2′-bipyridine) and Pt (O, O′-pd)(PPh3) 2, where N, N′ and O, O′ refers to
coordination of pd to the metal centre via N and O atoms, respectively, reveals that the
electron transfer processes between+ 0.5 and− 1.25 V all occur at the pd ligand in
agreement with DFT calculations. The two CO groups carry a significant amount of the …

Electrochemical and spectroelectrochemical (UV–Vis, IR, EPR) of pd (pd=1,10-phenanthroline-5,6-dione), Pt(N,N′-pd)Cl2, Pd(N,N′-pd)Cl2, [Ru(bpy)2(N,N′-pd)]Cl2 (bpy=2,2′-bipyridine) and Pt(O,O′-pd)(PPh3)2, where N,N′ and O,O′ refers to coordination of pd to the metal centre via N and O atoms, respectively, reveals that the electron transfer processes between +0.5 and −1.25V all occur at the pd ligand in agreement with DFT calculations. The two CO groups carry a significant amount of the negative charge in mono-reduced pd1−. The mode of coordination of pd has a greater influence on its redox chemistry than the metal centre or the ancillary ligands.
