[(μ2-H)(η2-Ge4)ZnPh2]3-, an Edge-On Protonated E4 Cluster Establishing the First Three-Center Two-Electron Ge-H-Ge Bond

Abstract

The first example of a protonated and a rare example of a metal complex of the tetrahedral tetrel cluster anion [Ge4]4 was obtained from a solution of K6Rb6Ge17 in liquid ammonia in the presence of ZnPh2 and [18]crown-6. In [K([18]crown-6)][Rb([18]crown-6)]2[HGe4ZnPh2] · 8 NH3 (1) one ZnPh2 molecule and one H atom are bound to opposite, significantly elongated edges of a distorted Ge4 tetrahedron. DFT calculations confirm the experimentally found interatomic distances and reveal a structural proof of a three-center two-electron Ge-H-Ge bond.
