英文摘要 Metal complexes containing thiyl radical play important roles for inducing protein
damage. In order to understand the reaction of thiyl radical with biomolecules, lots of
efforts have been devoted to understand the fundamental chemistry of metal thiolate
complexes that might potentially have metal-bound thiyl radical. Based on these
motivations, we have devoted to study vanadium thiolate complexes with the interest of
understanding vanadium chemistry relevant to biological systems. At this particular work,
four vanadium complexes have been synthesized and characterized. They are
[V(PS3”)(PS2”SH)] (1) , [VIV(PS3”)(S-SPS1”)] (2), [VIV(PS3”)(S-SOPS1”)] (3), and
[VIV(PS3”)(RPS1”)L] (4) (L = H2O or CH3CN). The molecular structures are shown
below. The chemistry of these complexes are further developed and reported here.
