摘　　要：通过配体1,3-苯二胺缩邻香兰素和Nd(OAc)3·H2O反应,合成了一个双核稀土配合物[Nd2L3(CH3OH)]·2CH3OH(1),X-射线单晶衍射分析确定了该配合物的晶体结构,配合物中两个钕(III)离子具有相同的配位构型,均为8配位的反四棱柱构型。荧光测试表明配合物1显示了钕(III)离子的近红外性质,固态时增强了配体到稀土Nd(III)离子的能级转移,同时在乙腈和乙醇溶液中也显示了钕(III)离子的特征发光,在乙腈溶液中的发光强度强于乙醇溶液。A dinuclear lanthanide complex[Nd2L3(CH3OH)]·2CH3OH(1)supported by salen-type(H2L=N,N′-bis(2-oxy-3-methoxybenzylidene)-1,2-phenylenediamine)ligand and Nd(OAc)3·H2O was structurally characterized.X-ray crystallographic analysis reveals that the two Nd(III)ions adopt same coordination environments that the octacoordinated Nd(III)ions are in a square antiprism geometry.Near-infrared(NIR)luminescent analysis reveals that complex 1 exhibit characteristic NIR luminescence of the Nd(III)ions enhanced energy transfer from the ligand to the Nd(III)ions in the solid state.The sale-type ligand can serve as an effeicient sensitizer for the characteristic luminescence of Nd(III)ions in CH3CN and CH3OH.The NIR luminescence intensity of complex 1 in CH3CN is stronger than that in CH3OH.
