Stepwise coordination of {Cu(C5Me5)} with tri-silylated Ge9 cluster
Abstract
Stepwise reaction between [Ge9Hyp3]– and CuI/K(C5Me5) yielded the {Ge9Hyp3} hybridized double-decker sandwich cluster [{Cu(C5Me5)}2(η3:η3-Ge9Hyp3)]– (2) via [Cu(C5Me5)(η3-Ge9Hyp3)]– (1) as intermediate. The controllable coordination of {Cu(C5Me5)} on tri-silylated Ge9 cluster in this work contributes to the rational design, synthesis and eventually the application of silylated Ge9 based catalysts.
