| Four Complexs with Triazine Derivative and Terephthalate：Synthesis, Structures, and Luminescent, Magnetic Properties | |
| 摘要: 通过水热合成法，合成了4个配位聚合物：[Mn（H2O）（PTZDA）（BDC）]n（1）、[Co（H2O）（PTZDA）（BDC）]n（2）、[Zn（H2O）（PTZDA）（BDC）]n（3）、[Cd（H2O）（PTZDA）（BDC）]n（4）（PTZDA=2，4-二氨基-6-（2’-吡啶）-均三嗪，H2BDC=对苯二甲酸），并分别用X射线单晶衍射、元素分析、红外光谱、差热分析和X-射线粉末衍射表征了这4个配合物。晶体结构分析表明，在配合物1~4中，配体PTZDA与中心金属离子螯合配位，金属离子通过配体BDC2-连结成一维链状结构，一维链之间通过氢键作用连接成三维超分子结构。磁性和荧光分析表明，配合物1和2具有非常弱的反铁磁作用；配合物3和4的荧光均为配体发光。 | |

| Abstract: Four polymers ([Mn(H2O)(PTZDA)(BDC)]n(1), [Co(H2O)(PTZDA)(BDC)]n(2), [Zn(H2O)(PTZDA)(BDC)]n(3), [Cd(H2O)(PTZDA)(BDC)]n(4) (PTZDA=6-(pyridyl-2-yl)-1,3,5-triazine-2,4-diamine, BDC=terephthalate) have been synthesized by hydrothermal reactions and structurally charecaterized by single crystal X-ray diffraction, elemental analysis, IR, TG and PXRD. Structural analysis reveals that the metal ions of compounds 1~4 are bridged by two carboxyl group from, terephthalate acid and are chelated by two nitrogen atoms from PTZD Aligand to form a one dimensional chain. These chains are further extended to 3D supramolecular structure by hydrogen bonds. The magnetic properties of compound 1~2 have been studied, indicating that they exist weak anti-ferromagnetism. Luminescent properties of compounds 3~4 indicates complex 3 and 4 possessing quality of photo-luminescent, which is assigned to the ligands. | |
