摘要
以席夫碱钠盐[NaL(THF)]2(L=3,5-t-Bu2-2-OC6H2CH=N-8-C9H6N)(1)为前体,与无水LnCl3(Ln=Eu,Yb)按物质的量比3∶2在四氢呋喃体系中室温反应24 h,高产率地得到均配型席夫碱稀土配合物LnL3[Ln=Eu(2),Yb(3)].两个配合物都通过了元素分析、红外光谱及单晶X射线衍射表征,其中配合物2属于三斜晶系,P 1空间群,a=1.28670(14)nm,b=1.32775(14)nm,c=2.3254(2)nm,α=93.435(2)°,β=96.487(2)°,γ=112.692(2)°.配合物3属于单斜晶系,P21/c空间群,a=1.72004(9)nm,b=1.81911(9)nm,c=2.85093(15)nm,β=106.376(1)°.
The reaction of anhydrous LnCl3(Ln=Eu,Yb) with [NaL(THF)]2(1)(L=3,5-t-Bu2-2-OC6H2CH=N-8-C9H6N) in a molar ratio of 2∶3 in THF at room temperature afforded the homoleptic Schiff base lanthanide complexes LnL3 [Ln=Eu(2),Yb(3)].These complexes were characterized by elemental analysis,IR spectra and X-ray structural determination.The crystal data of complex 2 are triclinic,P space group,a=1.28670(14) nm,b=1.32775(14) nm,c=2.3254(2) nm,α=93.435(2)°,β=96.487(2)°,γ=112.692(2)°.The crystal data of complex 3 are monoclinic,P21/c space group,a=1.72004(9) nm,b=1.81911(9) nm,c=2.85093(15) nm,β=106.376(1)°.
