摘要
使用 L_1、L_2两种配体,设计合成了九个草酰胺大环铜-稀土多核配合物,即四核配合物[(CuL_1)_3Ln(MeOH)_3](ClO_4)_3(MeOH)_2(Ln=Gd,Eu,sm,Nd)和五核配合物[(CuL_2)_3Ln(MeOH)(CuL_2ClO_4)](ClO_4)_2(MeOH)_2(Ln=Ho,Gd,Eu,Sm,Nd).分别解析了其中一个四核配合物和一个五核配合物晶体结构,[(CuL_1)_3Gd(MeOH)_3](ClO_4)_3(MeOH)_2(1)和[(CuL_2)_3Ho(MeOH)(CuL_2ClO_4)](ClO_4)_2(MeOH)_2(2),并进行了电子光谱、荧光光谱等性质研究.
By using a macrocyclic oxamide-Cu (Ⅱ) complex as ligand, four new quadrinu- clear complexes ]-(CuL1)3Ln(MeOH)3] (ClO4)3 (MeOH)2 (Ln = Ga,Nd,Sm,Eu) and five pentanuclear complexes [ (CuL2) 3Ln (MeOH) (CuL2ClO4)-] (ClO4) 2 (MeOH) 2 (Gd, Ho, Eu, Sm, Nd ) have been synthesized. Two of them {[(CuL1)3Gd (MeOH)3] (ClO4)3 (MeOH)2 (1) and [ (CuL2)3Ho (MeOH) (CuL2ClO4) ] (ClO4)2 (MeOH)2 (2)) have been determined by X-ray crystallographic methods and fluorescence quenching of them have been preliminary discussed.
