| 摘要: 以5-甲基-3-吡唑甲酸(H2MPCA)为主配体，桥联配体4，4’-联吡啶(4，4’-bpy)和吡嗪(pyz)为辅助配体，合成了2个新的配合物{[Co(HMPCA)2(4，4’-bpy)]2·5H2O}n(1)和{[Ni(HMPCA)2(pyz)]·5H2O}n(2)，并用元素分析、红外光谱、X射线单晶衍射结构分析、热重分析等对其进行了表征。配合物1属于正交晶系，空间群为Pccn，配合物2属于单斜晶系，空间群为P2/c。在1和2中，金属离子都位于一个扭曲的八面体配位环境中，分别由4，4’-联吡啶(1)和吡嗪(2)两端的氮原子桥联2个相邻的金属离子，形成一维链状聚合物。考察了配合物1和2的热稳定性、荧光性能和磁性。 | |

| Abstract: Two new 1D chain-typed coordination polymers, {[Co(HMPCA)2(4,4'-bpy)]2·5H2O}n (1) and {[Ni(HMPCA)2(pyz)]·5H2O}n(2) (H2MPCA=5-methyl-1H-pyrazole-3-carboxylic acid, 4,4'-bpy=4,4'-bipyridine, pyz=pyrazine), have been synthesized and characterized by elemental analysis, IR spectra, single crystal X-ray diffraction and thermogravimetric analysis. Complex 1 crystallizes in the orthorhombic system, space group Pccn, and 2 crystallizes in the monoclinic system, space group P2/c. In 1 and 2, metal ions are both located in an octahedral geometry, coordinated by two nitrogen atoms and two oxygen atoms from two HMPCA-anions, and linked by two nitrogen atoms from 4,4'-bpy ligands (1) and pyz ligands (2), respectively, forming a 1D chain-typed coordination polymer. The thermal stability, luminescent properties and magnetic properties of them have also been investigated. | |
