New Stable Germylenes, Stannylenes, and Related Compounds. 3. Stable Monomers XGeOCH₂CH₂NMe₂ (X = Cl, OCOMe) with Only One Intramolecular Coordination Metal−Nitrogen Bond: Synthesis and Structure

Abstract

New stable monomeric germanium(II) derivatives XGeOCH2CH2NMe2 (1, X = Cl; 2, X = OCOMe) with ligands that are not sterically bulky at the Ge atom and only one intramolecular coordination Ge←Nsp3 bond have been synthesized. The molecular and crystal structures of these compounds were studied by X-ray diffraction analysis. The electronic structures of 1 and 2 were studied by DFT. Compound 2 is the first structurally characterized acyloxy derivative of germanium(II).
