由水热法合成了钕化合物[Nd(HINAIP)(INAIP)(H2O)2]n·nH2O(1),(H2INAIP=5-异烟酰胺基异酞酸),并进行了元素分析、IR、TG及X-射线衍射法表征。晶体结构表明:配合物1属于三斜晶系,P1空间群。配合物1是由桥联配体5-异烟酰胺基异酞酸的羧基氧连接成二维层,此二维结构被氢键拓展成三维超分子结构。荧光光谱测试结果表明配合物1具有典型稀土钕的近红外荧光特征。
The neodymium compound [Nd (HINAIP) (INAIP) (H2O) 2] n · nH2O (1) and (H2INAIP = 5-isonicotinamido isophthalic acid) were synthesized by hydrothermal method. TG and X-ray diffraction characterization. The crystal structure shows that complex 1 belongs to triclinic system, space group P1. Complex 1 is bridged by the carboxy ligand of the ligand 5-isonicotinoylaminophthalic acid into a two-dimensional layer. The two-dimensional structure is extended to a three-dimensional supramolecular structure by hydrogen bonding. Fluorescence spectroscopy results show that the complex 1 has the near infrared fluorescence characteristics of typical rare earth neodymium.
