采用水热合成方法，以邻苯二甲酸和己二酸为配体，合成了1种具有3D无限结构的Nd（Ⅲ）配位化合物[Nd2（C8 H4 O4）2（C6 H8 O4）（H2 O）4]n ，并得到了它的单晶体。通过X射线单晶衍射，确定了该配合物的晶体结构，该配合物属于三斜晶系，P1空间群。在室温下，测定了配合物晶体粉末的IR光谱，UV-Vis-NIR吸收光谱及荧光激发和发射光谱，并进行了分析指认。该配合物在近红外区表现出明显的Nd（Ⅲ）离子特征发射，这应该是得益于配体的敏化作用。另外，配合物的近红外发射与理论发射相比出现了位移现象，可以从它的UV-Vis-NIR吸收光谱得到佐证，这应该是形成配合物后，在晶体场及Nd（Ⅲ）的4 f能级的相互影响下，体系内部能级得到调谐的结果。

Using o-phthalate and adipic acid as the ligands ,one Nd (Ⅲ ) coordination complex , [Nd2 (C8 H4 O4 )2 (C6 H8 O4 )(H2 O)4 ]n ,has been synthesized by the hydrothermal method .The struc-ture of the complex was determined by single crystal Xray diffraction .The complex crystallizes in the triclinic with P1 space group and possesses infinite 3D structure .At room temperature in the solid state ,the IR ,UV-Vis-NIR ,the excitation and emission spectra of the complex were measured and an-alyzed .The complex exhibits characteristic emissions of Nd(Ⅲ) ion in the NIR region ,which should be attributed to the sensitization of the organic ligands .In addition ,in comparison with the theoretical emission bands of Nd(Ⅲ) ion ,the NIR emission bands of the complex present shift ,which can be evi-denced by absorption bands of its UV-Vis-NIR spectrum .This may be attributed to crystal field and the interaction of 4f energy levels of Nd(Ⅲ) ions after the formation of the complex ,so the intra-lev-els are influenced .
