利用水热法合成了三维网状金属有机框架物[Nd（NTA）（H2 O）]∞[其中 NTA 指氨三乙酸根（nitrilotriacetate anion）]；采用元素分析仪、红外光谱仪和X射线单晶衍射仪等分析了产物的组成以及化学结构和晶体结构。结果表明，目标配合物中的NTA为四齿配体，Nd（III）原子采取八配位模式（NdN1 O7）形成十二面体立体结构。与此同时，[Nd（NTA）（H2O）]∞以菱形四面体 Nd8C14O28为构筑块，通过桥连羧基和分子间氢键组装成为三维超分子网络结构。

A three dimensional (3D) metal-organic framework of rhombic tetrahedral grid net-work ,coordination polymer [Nd(NTA)(H2 O)]∞ (NTA = nitrilotriacetate anion) ,was pre-pared by a hydrothermal method .The elemental composition as well as chemical structure and crystal structure of as-synthesized product were analyzed by elemental analysis ,infrared spec-trometry ,and single crystal X-ray diffraction .It was found that the NTA ligand in the target coordination compound acts as a tetradentate metal linker ,w hile the Nd(III) center in the com-plex adopts an eight-coordinated mode with NdN1 O7 donors to construct a distorted triangular dodecahedral configuration .In the meantime ,based on the building block of octanuclear homo-metallic Nd8 C14 O28 rhombic tetrahedral unit ,the neodymium coordination polymer is further assembled into highly ordered 3D architecture through O -C-O linkers and intermolecular hy-drogen bonds .
