  摘要：

  Synthesis of the title compounds, viz. [RN(CH2CHR'O)(2)](2)Ge (1, R = Me, R' = H; 2, R = Me, R' = Ph; 3, R = Ph, R' H), by the reaction of 2 equiv of corresponding dialkanolamines RN(CH2CHR'OH)(2) (4, R = Me, R' = H; 5, R Me, R' = Ph; 6, R = Ph, R' = H) with (AIkO)(4)Ge is reported. Composition and structures of all novel compounds were established by H-1 and C-13 NMR spectroscopy and mass spectrometry as well as elemental analysis data. The single-crystal X-ray diffraction of 2 has clearly indicated the presence of two transannular interactions Ge <- N in the compound. N atoms are cis-orientated. The compound 3 possesses long Ge center dot center dot center dot N distances. The structural data obtained from geometry optimizations by DFT calculations on 1-3 reproduces experimental results. Both cis- and trans-isomers were studied, and cis-configuration was found to be more thermodynamically stable for all three compounds. The transition states for possible cis <-> trans rearrangement processes in 1-3 were calculated. The properties of the Ge-O and Ge-N bonds in 1-3 were analyzed by the AIM approach. The interactions between the Ge atom and N atoms as well as 0 atoms possess predominantly ionic character.

  The reaction of dialkanolamines RN(CH2CH2O)(CHR'CHR'OH) (R = Me, Ph, PhCH2; R' = H, Ph) with tetraethoxygermane gives either 2,2-diethoxy-1,3,6,2-dioxazagermocanes RN(CH2CH2O)(CHR'CHR'O) Ge(OEt)(2) or 1,7,9,15-tetraoxa-4,12-diaza-8-germaspiro[7.7] pentadecanes [RN(CH2CH2O) (CHR'CHR'O)](2)Ge depending on the reactant ratio. The chemical behavior of the obtained compounds in substitution reactions at germanium was studied. The product structure was confirmed by elemental analysis data and H-1, C-13, and F-19 NMR spectroscopy. The cyclotrigermanoxane [MeN(CH2CH2O)(2)GeO](3) was studied by X-ray diffraction.
