摘要：
Protonation of [(Me(3)tacn)MoO3] with one or two equivalents of strong proton acid afforded mono-protonated complex [(Me(3)tacn)(MoO2)-O-VI(OH)](CF3SO3) and bi-protonated complex [(Me(3)tacn)(MoO)-O-VI(OH)(2)](PF6)(2), respectively. Sulfidation with (Pr2NCS)-Pr-i,Na or CS, in acetonitrile, followed by in situ protonation of [(Me(3)tacn)MO3] (M=Mo, W), produced two monomeric complexes [(Me(3)tacn)Mo-VI O2S]center dot((Pr2NH2)-Pr-i)center dot (PF6)center dot CH2Cl2 and [(Me(3)tacn)(WO2S)-O-VI], and two dimeric complexes [(Me(3)tacn)(WO2)-O-VI-(mu-S)(2)(MoO)-O-V(k(2)-S2C=O)]center dot CH3CN and [(Me(3)tacn)(MoO)-O-IV](2)(mu-O)(mu-S-2)center dot 2DMF. The crystal structures of the two protonated molybdenum(VI) complexes and the four oxo-sulfido molybdenum/tungsten complexes have been determined. Moreover, the complexes have been characterized by infrared, Raman, fluorescence and UV-vis spectroscopies. (Me(3)tacn =1,4,7-trimethyl-1,4,7-triazacyclonane).
