Many analytes that have basic sites prone to protonation, display pH-dependent electrochemistry. The redox properties of metal complexes of H2O, OH, and often display pH-dependent electrochemistry as demonstrated by Meyer et al. for the complex [M(tpy)(bpy)0] + (M = Ru or Os tpy = 2,2, 2"-terpyridine). These complexes have been studied probing their electrochemistry over a wide range of pH. CV and DPP were used to determine Ei/2 for the Ru and Ru redox couples of the complex [Ru(tpy)(bpy)0] + from pH 0 to 13 (Figure 4) and the Nemst equation (2) was used to fit the data. 

This chapter is dedicated to the memory of my father, Professor Antonin A. Vlcek (1927-1999), who has contributed much to the electrochemistry of metal-polypyridine complexes and to our understanding of underlying principles [1, 4-8, 15-29, 209],... 

By using a combination of known reactions, synthetic chemistry, and electrochemistry, new catalysts for the electrochemical reduction of CO2 have been developed. Consideration of the electrochemical properties of a variety of transition metal complexes containing polyphosphine ligands led to a more detailed study of metal complexes of the type [M(PP2)(PR3)HbF )2 (where M is Ni, Pd, and Pt ... 

The purpose of this monograph is to present some recent results involving the redox chemistry of some metal ion complexes, some of which contain very traditional and well established ligands, such as bipyridine (bipy), while others involve more esoteric ones, such as the cryptands. However, the main theme is not necessarily the electrochemistry of these complexes, nor their electron spin resonance (ESR) spectra, but rather the properties of the resulting redox products, whether in solution or in the solid state. Some of these redox products have been successfully crystallized, and some of their solid state properties have been measured, including X-ray diffraction and conductivities. These will be briefly presented. In addition, some of the properties of these reduced complexes in solution will also be presented and discussed. 

Although, as already mentioned, the iron II and III oxidation states are so dominant, we will nevertheless attempt to equally treat in this chapter, the electrochemistry of iron complexes in every documented oxidation state. Besides, despite the fact that iron will be considered almost exclusively, the redox chemistry of the other metals of the iron group, ruthenium and osmium, will also be discussed, together with its applications in bioelectrochemistry.
