The active sites of the xanthine oxidase and sulfite oxidase enzyme families contain one pterin-dithiolene cofactor ligand bound to a Mo atom. Consequently, monodithiolene Mo complexes were sought by exploratory synthesis for structural and reactivity studies. Reaction of [MoO(S2C2Me2)2]1- or [MoO(bdt)2]1- with PhSeCl results in removal of one dithiolate ligand and formation of [MoOCl2(S2C2Me2)]1- (1) or [MoOCl2(bdt)]1- (2), which undergoes ligand substitution reactions to form other monodithiolene complexes [MoO(2-AdS)2(S2C2Me2)]1- (3), [MoO(SR)2(bdt)]1- (R = 2-Ad (4), 2,4,6-Pri3C6H2 (5)), and [MoOCl(SC6H2-2,4,6-Pri3)(bdt)]1- (6) (Ad = 2-adamantyl, bdt = benzene-1,2-dithiolate). These complexes have square pyramidal structures with apical oxo ligands, exhibit rhombic EPR spectra, and 3–5 are electrochem. reducible to MoIVO species. Complexes 1–6 constitute the 1st examples of five-coordinate monodithiolene MoVO complexes; 6 approaches the proposed structure of the high-pH form of sulfite oxidase. Treatment of [MoO2(OSiPh3)2] with Li2(bdt) in THF affords [MoO2(OSiPh3)(bdt)]1- (8). Reaction of 8 with 2,4,6-Pri3C6H2SH in MeCN gives [MoO2(SC6H2-2,4,6-Pri3)(bdt)]1- (9, 55%). Complexes 8 and 9 are square pyramidal with apical and basal oxo ligands. With one dithiolene and one thiolate ligand of a square pyramidal MoVIO2S3 coordination unit, 9 closely resembles the oxidized sites in sulfite oxidase and assimilatory nitrate reductase as deduced from crystallog. (sulfite oxidase) and Mo EXAFS. The complex is the 1st structural analog of the active sites in fully oxidized members of the sulfite oxidase family. This work provides a starting point for the development of both structural and reactivity analogs of members of this family.
