Reductive halogen elimination from 1 offers a surprisingly simple route to the polycyclic germane 2. Compound 2 is air‐stable and decomposes above 400°C. Its C 2 symmetry is revealed in the presence of only four NMR signals for the tert ‐butyl protons.\documentclass{article}\usepackage{amssymb}\pagestyle{empty}\begin{document}$$t{\rm BuBr_2Ge-GeBr_2}t{\rm Bu}\quad{\bf 1}$$\end{document}
