[GeN(SiMe3)}22(μ-Te)]2 (3) and 7,by single crystal X-ray diffraction. Some selected geometric parameters are as follows. 3: Ge-N 1.86(1), Ge-Te 2.595(2), Si—N 1.76(2) Å; TeGeTe′ 94.38(6), GeTeGe′ 85.59(6)°. 7: (MeO)C-C(OMe) 1.40(2), CC—C(OMe) 1.36(2), MeOCO-Sn 2.125(9), Sn-C 2.07(1), Sn-N 2.031(9), Si-N 1.75(1)Å. Each of the compounds Sn(η-C5H4R)(NR2) (8) and Sn(η-C5H3R2-1,3)(NR2) (9) was obtained in a mixture with
锗和锡的二价酰胺M(NR 2)2(R = SiMe 3,M = Ge或Sn)容易与硫族元素(E)或MeOOCCCCOOMe反应生成适当的金属(IV)氧化加成产物[M( NR 2)2(μ-E)] n(E = S,Se或Te)(1-6)或(7)。每个化合物1–7均已通过微分析和NMR光谱进行了表征,其中两个化合物[Ge N(SiMe 3)} 2 2(μ-Te)] 2(3)和7均通过单晶X射线表征衍射。一些选定的几何参数如下。3:Ge-N 1.86(1),Ge-Te 2.595(2),Si-N 1.76(2)Å;TeGeTe'94.38(6),GeTeGe'85.59(6)°。7:(MeO)CC(OMe)1.40(2),CC-C(OMe)1.36(2),MeOCO-Sn 2.125(9),Sn-C 2.07(1),Sn-N 2.031(9),Si -N 1.75(1)Å。各化合物的Sn(η-C
