The 1:2 reaction of the imidazole‐based dithiolate (2) with GeCl2•dioxane in THF/TMEDA gives 3, a TMEDA‐complexed dithiolene‐based germylene. Compound 3 is converted to monothiolate‐complexed (5) and N‐heterocyclic carbene‐complexed (7) germanium(II) dithiolene complexes via Lewis base ligand exchange. A bis‐dithiolene‐based germylene (8), involving a 3c‐4e S––Ge–S– bond, has also been synthesized through controlled hydrolysis of 7. The bonding nature of 3, 5, and 8 was investigated by both experimental and theoretical methods.
