Abstract

Differences in the redox properties of Mo and W and the degree to which they participate in M−S redox impact their behavior in biological systems. Here, we report the synthesis and characterization of the oxo−thio−W(VI) complexes, Tp*WVIOS(S2PR2-S) (I) and Tp*WVIOS(pyS-S) (II), and aspects of their redox chemistry. These complexes are less susceptible to reduction than their Mo “counterparts” and are stable in the absence of WS···S interactions. They are reduced to the corresponding oxo−thio−W(V) anions and oxidized to (dithio)oxo−W(V) complexes in induced internal redox reactions.
