6H4CH=N-CH2CH2)C8H5]RE[N(SiMe3)2]2(µ-Cl)Li(THF)} (RE = Y(1), Sm(2), Gd(3), Er(4), Yb(5)). By extending the reaction time, only the reaction of HL with [(Me3Si)2N]3Gd(µ-Cl)Li(THF)3 gave an unexpected binuclear rare-earth metal complex [(µ-η5:η1):η1:η1-3-[(Me2N)2-C14H9]-(NCH2CH2-C8H5N)2]Gd2[N(SiMe3)2]3} (6) incorporating a novel polycyclic ligand through C-C and C-N coupling. Treatment of HL with [
亚氨基官能化的吲哚基配体(H L,L = 3-(4-Me 2 N-C 6 H 4 CH = N-CH 2 CH 2)C 8 H 5 N)与稀土金属酰胺的反应[(研究了产生不同类型稀土金属酰胺配合物的Me 3 Si)2 N] 3 RE(µ -Cl)Li(THF)3。H L与1当量的反应。[(Me 3 Si)2 N] 3 RE(µ -Cl)Li(THF)3的原子数产生了一系列的异核双金属稀土类金属的氨基络合物[ η 1:μ - η 2 -3-(4-我2 N-C 6 H ^ 4 CH = N-CH 2 CH 2)C 8 H ^ 5 ] RE [N(SiMe 3)2 ] 2(μ- Cl)Li(THF)}(RE = Y(1),Sm(2),Gd(3),Er(4),Yb(5))。通过延长反应时间,仅H L与[(Me 3 Si)2 N] 3的Gd(μ -Cl)的Li(THF)3,得到意想不到的双核稀土类金属络合物[(μ
