In nature, metal–sulfur clusters provide the active sites of several enzymes which catalyze important reactions such as, for example, H+/H2 conversion by hydrogenases and nitrogen fixation by the nitrogenases. The understanding of the functioning of these metalloenzymes and the design of active bioinspired molecules are great challenges for chemists, and they require a multidisciplinary approach at the interface of chemistry and biology.
The focus of this book is to highlight the more recent developments in metal–sulfur complexes involved in bioinspired catalysis.
As an introductory part, the first chapter shows the possible importance of metal-sulfides in the chemautotrophic origin of life. In this context, the iron–sulfur world theory is emphasized. This introductory part is completed by the second chapter concerning biogenesis and redox, catalytic, and regulatory properties of Fe–S clusters. The second part deals with impressive advances that have been reported during the past 15 years in the molecular chemistry of models of the active sites of the different classes of hydrogenases. Advances into the electrocatalytic H2 production and uptake are reported. A third part is intended to provide recent insights concerning N2-fixation by nitrogenases for which understanding their functioning is still one of the most exciting and intricate modern challenges in bioinorganic chemistry. Recent X-ray analyses of the structure of the FeMo cofactor have led to a kind of renaissance of this field. In the two previous parts, syntheses as well as analytical and theoretical aspects of structural and functional models of these enzymes are described. The fourth part deals with metal–sulfur-containing enzymes activating nitriles (nitrile hydratase) of molybdenum and tungsten enzymes, which contain the pyranopterin cofactor and perform a wide variety of biological functions. They catalyze a diversity of mostly two-electron oxidation–reduction reactions crucial in the metabolism of nitrogen, sulfur, and carbon (xanthine oxidase, dimethyl sulfoxide reductase, sulfite oxidase, and nitrate reductases). In the final chapter, some applicative perspectives of bioinspired complexes, as electrode materials, and artificial photosynthetic systems, are illustrated.
Finally, we thank the authors for their contributions to this book and their efforts and we hope that the readers will find in it a source of recent knowledge in this area of chemistry and of inspiration.

The archaeologist of nature is at liberty to go back to the traces that remain of nature's earliest revolutions, and, appealing to all he knows or can conjecture about its mechanism, to trace the origin of that great family of creatures…down even to mosses and lichens, and finally down to the lowest perceivable stage of nature, to crude matter. From this and from the forces within, by mechanical laws, like those that are at work in the formation of crystals, seems to be derived the whole technique of nature.
Immanuel Kant [1]
Darwin (1863) wrote in a letter to Hooker [2]: “It is mere rubbish, thinking at present of the origin of life; one might as well think of the origin of matter.” Studies of nucleosynthesis are now quite advanced, but research into the origin of life is still an immature science. The problem of early evolution of life is unique and requires its own heuristic. A commonly used heuristic consists of one-to-one back-extrapolations of individual biochemical features (a), for which Lipmann [3] coined the term . More and more backward projections add evermore ingredients to the recipe. Inevitably, this way of thinking leads to the notion of a “primordial broth.” No one has ever spelled out all that what would or would not have been in the broth and how precisely the organization of life could have come about within such a chaotic situation.
