【摘要】 三乙基四胺和3-羧基水杨醛以1:3缩合得到结构新颖的席夫碱配体L(L=3,3’,3"-(1E,1’E,1"E)-(2,2’,2"-nitrilotris(ethane-2,1-diyl)tris(azan-1-yl-1-ylidene))tris(methan-1-yl-1-ylidene)tris(2-hydroxybenzoic acid)),并以它的镍单核配合物为构筑块,设计合成过渡稀土混金属配合物[Gd2Ni4L2(OH)2(H2O)2]·7.5H2O,通过X-射线单晶衍射测定配合物的结构,并通过红外光谱、紫外光谱、热分析、荧光性质和磁学性质的表征和测试,并对它们的性质进行比较和研究。
【Abstract】 Through condensing triethylenetetramine and 3-carboxysalicylidene(1:3),one new Schiff base ligand H6L1[H6L1=3,3′,3″-(1E,1′E,1″E)-(2,2′,2″-nitrilotris(ethane-2,1-diyl)tris(azan-1-yl-1-ylidene)) tris(methan-1-yl-1-ylidene)tris(2-hydroxybenzoic acid)],using the NiL precursor as a building block,we have synthesized heterohexanuclear complex[Gd2Ni4L2(OH)2(H2O)2]·7.5H2O.The crystal structure has been determined by X-ray analysis.The complex has been characterized and tested by IR,UV-Vis, fluorescent spectra and magnetic property,and its properties has been analysed and researched.
