摘　　要：采用水热合成法,得到3种Ni-Ln(Ⅲ)[Ln(Ⅲ)=Tb,Eu,Nd]配合物[Tb2(C6H5COO)8][Ni(phen)3].4H2O(1);[Eu2(C6H5COO)8][Ni(phen)3].4H2O(2);[Nd2(C6H5COO)8][Ni(phen)3].4H2O(3).所合成的这3种配合物结构基本相同,均为离子型配合物.在配阴离子中,每个Ln(Ⅲ)离子与8个羧基氧配位,生成双核配离子.在配阳离子中,Ni与phen配位,形成了畸变的八面体构型.对这3种配合物的单晶进行了X-射线衍射分析,确定了晶体结构,它们有相似的结构.同时对配合物紫外吸收光谱(UV-VIS-NIR),红外(IR)光谱和荧光(FP)光谱进行了测定和分析指认.Three complexes Ni-Ln（Ⅲ）（Ln（Ⅲ）=Tb,Eu,Nd）,[Tb2（C6H5COO）8][Ni（phen）3]·4H2O（1）;[Eu2（C6H5COO）8][Ni（phen）3]·4H2O（2）;[Nd2（C6H5COO）8][Ni（phen）3]·4H2O（3） have been synthesized by hydrothermal method.The crystal structures of the three complexes were determined by X-ray diffraction.They possess similar molecular structures,which are ionic complexes.In the coordinate anion,each Ln（Ⅲ） ion is coordinated by oxygen atoms from carboxyl,which builds dinuclear coordinate anion.In the coordinate cation,Ni ion is coordinated by phen,which forms a distorted octahedral configuration.At the same time,the UV-VIS-NIR,IR and fluorescence spectra of the three complexes were measured and analyzed.All the spectral bands were analyzed,assigned and listed in this paper.
