New Intermetalloid Ge9‐clusters with Copper and Gold: Filling Vacancies in the Cluster Chemistry of [Ge9(Hyp)3]− (Hyp=Si(SiMe3)3)

We present a series of new intermetalloid clusters (R3P)CuGe9((Hyp)3, (R=Me, Et, iPr, nBu, tBu) (Hyp=Si(SiMe3)3) (R3P)AuGe9(Hyp)3MGe9(Hyp)3 (R=Ph, Me; M=Au, Cu). In conjunction with already known clusters, these give new insights into the bonding situation of metal bridged Ge9 clusters as well as a...

Description
Summary:We present a series of new intermetalloid clusters (R3P)CuGe9((Hyp)3, (R=Me, Et, iPr, nBu, tBu) (Hyp=Si(SiMe3)3) (R3P)AuGe9(Hyp)3MGe9(Hyp)3 (R=Ph, Me; M=Au, Cu). In conjunction with already known clusters, these give new insights into the bonding situation of metal bridged Ge9 clusters as well as a better understanding of the formation of these clusters. Additionally, the intermetalloid clusters with the smallest phosphine PMe3 show new bonding motives. The reaction of KGe9(Hyp)3 (Hyp=Si(SiMe3)3) with (R3P)MCl (R=Me, Ph, Et, iPr, tBu; M=Au, Cu) leads to different products of the composition (R3P)MGe9(Hyp)3, (R3P)MGe9(Hyp)3MGe9(Hyp)3, or [Ge9(Hyp)3MGe9(Hyp)3]−. One, two or all three compounds were isolated from the same reaction solution and characterized.
