Abstract
The contents of this chapter include synthesis, structure and reactivity of molybdenum complexes which were reported from 2002 to 2020 as a continuation to Comprehensive Coordination Chemistry, (CCC, 1987) 1 and Comprehensive Coordination Chemistry II, (CCC II, 2003). 2 A comprehensive review of the Mo coordination/organometallic chemistry is attempted but excludes reports focused on material/nano chemistry although they have attracted increasing interest in modern chemistry, as they are out of the scope of this chapter. Along with the ongoing progress in the high-valent chemistry, the rapid development of low-valent Mo chemistry in the past two decades is exhaustively reviewed. The features of complexes in a series are often discussed by their representative compounds. Reports pertaining to the crystallographic details and in Inorganic Synthesis are not included but can be traced back using the citations included. Molybdenum complexes have wide applications in industry, most prominently as catalysts in olefin metathesis, epoxidation, sulfoxidation and oxidation processes. 3–5 Mo is a trace element essential for lifecycle of different living beings and also is a cofactor for many enzymes (e.g.: nitrate reductase nitrogenase, sulfite oxidase and xanthine oxidase) and is responsible for the health and life cycle of living beings. Many complexes are being designed for mimicking and detailed model study of these molybdoenzymes in living organisms. Introduction of a wide variety of ligands to support Mo complexes facilitated the advent of novel systems with interesting characteristics of which the applications and potentials are not yet fully explored. The introduction of multiple bonded Mo-complexes and their....
