A lithium‐containing intermediate 1 can be isolated in the synthesis of a trigermole from 1,1‐dichloro‐tetraethylgermole. NMR and X‐ray diffraction studies reveal that one Li cation is part of a lithocene structure, while the second is in an environment similar to common organolithium compounds. In the solid state, the second lithium center is tetrahedrally coordinated to two nitrogen atoms of TMEDA, the oxygen atom of THF, and the Ge atom of one of the π‐complexed germole rings.
