Silylene-Induced Reduction of [Mn2(CO)10]: Formation of a Five-Coordinate Silicon(IV) Complex with an O-Bound [(OC)4Mn=Mn(CO)4]2– Ligand

Treatment of the donor-stabilized silylene [iPrNC(NiPr2)NiPr](2)Si (1) with [Mn-2(CO)(10)] leads to the five-coordinate silicon(IV) complex 6, accompanied by elimination of two CO molecules. In this redox reaction, the dimanganese fragment is reduced to form an [(OC)(4)Mn=Mn(CO)(4)](2-) moiety that is coordinated to the silicon(IV) species {[iPrNC(NiPr2)NiPr](2)Si}(2+).
