Abstract
We report the reactions of K[Ge(Hyp)] (Hyp = Si(SiMe)) with (thf)YbI, ThI, and UCl, leading to the oxidative coupling of the metalloid germanium cluster to form the dimeric dianion [Ge(Hyp)]. The novel dimerized Ge-cluster was isolated and characterized by single-crystal X-ray diffraction analysis as a component of ionic compounds [Yb(thf)][Ge(Hyp)] () and [K(2.2.2-crypt)][Ge(Hyp)] () with two different counterions. The dihedral angle between two intact Ge cages depends on the counterions, which was also studied by quantum-chemical calculations.
