| 摘 要： | 2，3，5-吡啶三酸在水热条件下分别与Mn（CH3COO）2·4H2O和Co（CH3COO）2·4H2O反应，得到了2种金属有机骨架（MOFs）配合物Mn1.5（2，3，5-pta）（H2O）4]n（1）和Co1.5（2，3，5-pta）（H2O）4]n（2），其中2，3，5-H3pta=2，3，5-吡啶三酸。利用元素分析、红外、热重和X-射线单晶衍射分析进行了表征。分析结果表明2个配合物属于同构晶体：晶系为单斜，空间群为P21/c，其中，吡啶三酸配体完全脱去3个质子，并分别与4个六配位的金属离子相连，在空间形成一种三维网络状结构。热重分析表明，配合物1的稳定性要高于配合物2。

| Abstract: | Reactions of 2,3,5-pyridinetricarboxylic acid and Mn(CH3COO)2·4H2O or Co(CH3COO)2·4H2O under hydrothermal conditions, yielded two new metal organic frameworks of Mn1.5(2,3,5-pta)(H2O)4]n (1) and Co1.5(2,3,5-pta)(H2O)4]n (2;2,3,5-H3pta=2,3,5-pyridinetricarboxylic acid), respectively, which have been structurally charac-terized by elemental analysis, infrared spectroscopy, thermogravimetric analysis and single-crystal X-ray diffraction. The results of structural analysis reveal that two complexes are isostructural which both crystallized in monoclinic system with space group of P21/c. In the complexes, 2,3,5-pyridinetricarboxylic acid ligand lost all three protons and connected with four 6-coordinated metal ions to form a kind of three dimensional framework. And the thermal gravimetric analysis has shown that the complex 1 is more stable than complex 2. |
