Abstract:	New stable azido derivatives of divalent germanium and tin [N₃-E¹⁴-OCH₂CH₂NMe₂]₂ (E¹⁴ = Ge (1), Sn (2)) have been synthesized by use of the β-dimethylaminoethoxy ligand that forms the intramolecular E¹⁴ ← N coordination bond. Their crystal structures have been determined by X-ray diffraction analysis. Compounds 1 and 2 are centrosymmetric dimers via two intermolecular dative E¹⁴ ← O interactions with essentially linear monodentate azide ligands. The dominant canonical form of the E¹⁴-azide moieties is E¹⁴-N-NN.

Keywords:	Germanium(II) and tin(II) azides β-Dimethylaminoethoxy-ligand X-ray analysis
