摘要 无水NdCl3与 (Me3Si) 2 NLi在THF中反应 ,并在甲苯中回流 ,可以得到具平面型三配位的[(Me3Si) 2 N]3Nd ,其结构经X -衍射确定 .晶体结构数据 :C18H54 N3NdSi6 ,Mr =6 2 5 .4 2 ,六方晶系 ,空间群P 3-1c ,a =16 .4 87(2 ) ,c =8.4 76 3(17) ,α =β =90° ,γ =12 0° ,V =1995 .3(3) 3,Z =2 ,Dc =1.0 4 1g/cm3,F (0 0 0 ) =6 5 4,μ (MoKα) =1.4 89mm- 1.晶体结构分析表明 ,在[(Me3Si) 2 The three coordinate planar neodymium amide [(Me 3Si) 2N] 3Nd was prepared by the reaction of anhydrous NdCl 3 with three equiv of (Me 3Si) 2NLi in THF, followed by reflux in toluene. Its structure was determined by single crystal X ray diffraction. Crystallographic data: C 18 H 54 N 3NdSi 6, Mr=625.42, Hexagonal, space group P 3 -1c, a=16.487(2),c=8.4763(17),α=β=90°,γ=120°,V995.3(6) 3,Z=2,D c=1.041 g/cm 3,F(000)=654,μ(MoKα)=1.489 mm -1 . Crystal structure analysis shows that the NdN 3 skeleton in [(Me 3Si) 2N] 3Nd is planar.
