✦ Synopsis
This article tries to rationalize why low molecular weight complexes have not yet been able to copy nitrogenase catalyzed reactions or to act as competitive catalysts with nitrogenaselike activity. An answer is sought in that such complexes must rather fulfil the principles governing FeMoco function than duplicate its structure. Such principles, e.g. metal sulfur bonds, reversible M-S bond dissociation, Brønsted basicity, vacant sites, redox activity, are illustrated with metal complexes of multidentate thioether thiolate ligands.
