Oxomolybdenum(III, IV and V) complexes of thiofunctional ligands

• Reaction of [MoO2(acac)(2)] with Li2NS2S'(2), (S is a thioether, S' a thiophenolate function) yielded the compound Li-7(thf)(17){MoO}(8)center dot 10thf center dot hexane, where {MoO}(8) represents one [(MoO)-O-IV(NS2S'(2))] 1, three [(MoO)-O-III(NS2S'(2))](-) (2, linked, via the oxo group, to [Li(thf)3](+)) and two [(MoO)-O-V(S'(2))(2)](2-)(2) .A mixed-valent variant of 3, [{(MoO)-O-IV(S'(2))} {(MoO)-O-V(S'(2))}](-) (3b, with an additional [Li(thf)3](+) attached to S'), was also identified. The compounds model features pertinent to oxo-transferases containing the molybdopterin cofactor.
