Abstract
The occurrence of molybdenum in at least six metalloenzymes having redox function (nitrogenase, nitrate reductase, xanthine oxidase, aldehyde oxidase, sulfite oxidase, and formate dehydrogenase)1 has created a need for greater understanding of the oxidation-reduction chemistry of this element. This realization prompted us to begin an investigation of electrochemical behavior of suitable inorganic i.e., model) molybdenum complexes with the expectation that the results would be useful in interpreting the redox behavior of this element in its various enzymes. A number of important questions can be addressed using contemporary electro chemical techniques such as cyclic voltammetry, potential step electrolysis, and controlled potential coulometry. These questions include: (1) whether electron transfer into the molybdenum center occurs by multiple steps involving a single electron or by a single multi-electron step; (2) the redox potentials of the electron transfer steps; (3) whether electron transfer leads to species with unusual stability or reactivity; and (4) the extent to which processes in (1)–(3) are influenced by molecular structure and solution environment. Trends have emerged with important implications for the redox properties of molybdoenzymes.
