Molybdenum or tungsten is present at the active sites of over 30 distinct enzymes. The Mo enzyme nitrogenase, with its unique polynuclear metal sulfide clusters, falls in a class by itself All other Mo and W enzymes are mononuclear, with pterin-ene-dithiolate coordination. Recent x-ray crystallographic results on several of these enzymes confirm the potential additional presence of 0x0 (one or two), sulfido, cysteine, selenocysteine, serine, aquohydroxo, and/or a second dithiolene in the…

TLDR
During the global transition to oxic conditions, reduced Mo species were constrained to specific anaerobic habitats, and efficient uptake systems of oxidized Mo(VI) became a selective advantage for current prokaryotic and eukaryotic cells.

An overview of the pyranopterin dithiolene (MPT) component of the molybdenum cofactor (Moco) and how MPT may contribute to enzymatic catalysis is presented. The chapter begins with a brief review of
Synthesis and structure of mononuclear molecular complexes of molybdenum(VI) and tungsten(VI) oxy- and dioxyhalides
Specific features of the synthesis and structure of mononuclear molecular halide oxide complexes of Group VI d0 metals molybdenum(VI) and tungsten(VI) are surveyed. Various methods of synthesis of
S-Donor Ligands
The chemistry of S-donor ligands with metal centres is reviewed with emphasis placed on the structures and redox activity of the resultant complexes. Sulfides and thiolates bind to a wide range of
Aldehyde Ferredoxin Oxidoreductase
Aldehyde ferredoxin oxidoreductase (AOR) is a homodimer where each subunit contains a [4Fe–4S] cluster and a mononuclear tungsten atom coordinated by the dithioline groups of two pterin molecules.

TLDR
Metallo-dithiolene non-innocence is explored in an oxomolybdenum-bis(dithione) complex, [Mo4+O(i-Pr2Pipdt)2Cl][PF6], that possesses a piperazine ring as an integral part of the dithiolenes ligand.
