Abstract

The oxidation of closo-heteroborates [GeB₁₁H₁₁]^2- and [SnB₁₁H₁₁]^2- is presented. Upon oxidation germa-closo-dodecaborate yields a symmetrical dimer exhibiting a Ge-Ge bond between two clusters. This dimer shows sulphur insertion into the Ge-Ge bond at room temperature. In contrast, oxidation of the homologous tin cluster results in an unsymmetrical dimer bearing an Sn-B bond between two clusters. The Sn-B dimer is also the product of the hydride abstraction reaction. In the presence of the donor ligand 2,2′-bipyridine, the oxidation of closo-cluster [SnB₁₁H₁₁]^2- leads to the Sn(iv)-half sandwich coordination compound [bipy-SnB₁₁H₁₁] which dissolves in DMSO to give the Sn(iv)-adduct [bipy(DMSO)-SnB₁₁H₁₁].
