Abstract: New 10π-electron stabilized O,N-heterocyclic germylene was synthesized and structurally characterized for the first time. Its reduction with potassium in THF resulted in a unique low-valent germanium compound comprising the conjugated Ge₄ chain, which was also characterized by the single crystal X-ray analysis. Bonding aspects in the latter compound have been additionally explored by DFT calculations, which revealed the occurrence of three σ bonds of different (covalent and dative) characters between the Ge atoms.

Keywords: germylene, o-amidophenolate ligand, low-valent, X-ray, DFT.
