Ge(I) BROMIDE: A NEW SOURCE FOR GERMANIUM CLUSTER COMPOUNDS

Abstract

Ge(I)Br represents a good starting material for the synthesis of Ge cluster compounds which feature in addition to ligand bound Ge atoms also naked Ge atoms. The synthetic concept, the structures, and bond properties of a Ge₈ and a Ge₉ cluster compound are reported.

Notes

*Beside the approach via the disproportionation reaction other pathways to get to Ge cluster compounds with an average oxidation state of the Ge atoms inside the cluster core between 0 and 1 ([Ge₁₀R₆]⁺, ^7a Ge₆R₂ ^7b ) are possible.
