  摘要：

  A series of germanes Ar3GeX, containing electron-withdrawing substituents [Ar = p-FC6H4, 1a-d, 1a (X = CO, 1b (X = Br), 1c (X = H), 1d (X = NMe2); p-F3CC6H4, 2a-d, 2a (X = Cl), 2b (X = Br), 2c (X = H), 2d (X = NMe2)], was synthesized and used to prepare symmetrical digermanes Ar3Ge-GeAr3, (p-FC6H4)(3)GeGe(C6H4F-p)(3) (3), and (p-F3CC6H4)(3)GeGe(C6H4CF3-p)(3) (4) and trigermane [(p-F3CC6H4)(3)Ge](2)Ge(C6F5)(2) (5) by hydrogermolysis reaction. The properties of all compounds were investigated by multinuclear NMR and for oligogermanes by UV/vis and fluorescence spectroscopy, as well as by electrochemical methods. In addition, the molecular structures of 1a, 1b, 2b, 2c, and 3-5 were studied by X-ray diffraction analysis. Compound 5 showed a significantly shifted UV/visible absorption to the red field in comparison with previously described derivatives.

  The linear oligogermyl amide 2, Ph3GeGeMe2NMe2, was obtained by reacting Ph3GeLi with 1, Me2Ge(Cl)NMe2. The amide 2 was used for the synthesis of molecular oligogermanes 3, Ph3GeGeMe2Ge(C6F5)3, and 4, [Ph3GeGeMe2]2Ge(C6F5)2, containing electron donor (Me, Ph) and acceptor (C6F5) groups, by using a hydrogermolysis reaction in n-hexane. The molecular structures of 3 and 4 were studied by XRD. It was

  The reaction of GeHal₄ with MeN(CH₂CH₂OSiMe₃)₂ affords dihalogermocanes MeN(CH₂ CH₂O)₂GeHal₂ (1, Hal = Br; 2, Hal = Cl). Treatment of Me₂Ge(NMe₂)₂ with MeN(CH₂CH₂OH)₂ leads to dimethylgermocane MeN(CH₂CH₂O)₂GeMe₂ (3). The composition and structure of 1-3 were established by elemental analyses, ¹H, ¹³C NMR spectroscopy, and mass spectrometry. The crystal structure of 1 is reported; structural data obtained from geometry DFT optimization on 1 are in good agreement with experimental results. Values of the electron density in the N→Ge bond critical point and the Laplacian of charge density for 1-3 indicate a closed-shell interaction between the Ge and N atoms.

  GeHal₄与MeN(CH₂CH₂OSiMe₃)₂反应生成二卤代锗烷MeN(CH₂ CH₂O)₂GeHal₂（1，Hal = Br; 2，Hal = Cl）。Me₂Ge（NMe₂）₂与MeN(CH₂CH₂OH)₂反应生成二甲基锗烷MeN(CH₂CH₂O)₂GeMe₂（3）。通过元素分析、¹H、¹³C NMR光谱和质谱确定了1-3的组成和结构。报道了1的晶体结构；从1的几何DFT优化得到的结构数据与实验结果吻合良好。1-3的电子密度在N→Ge键临界点和电荷密度的Laplacian值表明Ge和N原子之间存在闭壳层相互作用。
