| 摘要: Co（OAc）2·2H2O，4，4'-偶氮吡啶（4，4'-azpy）和N-3-吡啶磺酰化氨基乙酸（H2L）在乙醇和水混合溶液中反应生成了一个单核钴配位聚合物{[Co（L）（4，4'-azpy）（H2O）]·2H2O}n（1）。利用元素分析、IR、热重和单晶X射线衍射对其结构进行分析。结果表明该配位聚合物属于单斜晶系，P21/n空间群。热重分析结果表明，配位聚合物在失去配位水分子和游离水分子后结构仍然保持不变，并在238℃开始分解，具有良好的稳定性。磁性测试表明在配合物的中心离子Co（Ⅱ）之间存在反铁磁相互作用。 | |

| Abstract: The reaction of Co(OAc)2·2H2O, 4,4'-azopyridine(4,4'-azpy) with N-(pyridine-3-sulfonyl amino) acetate (H2L) in ethanol and water leads to the formation of one mononuclear cobalt polymer {[Co(L)(4,4'-azpy)(H2O)]·2H2O}n (1). The structure of 1 was analyzed by elemental analysis, IR, TG and single crystal X-ray diffraction. The results show that complex 1 belongs to monoclinic system and P21/n space groups. The TGA shows that the structure of 1 remains unchanged during the loss of coordination water molecules and free water molecules, and begins to decompose at 238℃, indicating 1 has good stability. The magnetic investigation shows that there is antiferromagnetic interactions between Co(Ⅱ) ions in polymer 1. | |
