摘要: 以2,4,6-吡啶三酸为配体,采取水热合成的方法,在相同温度、物质的量之比、溶剂,不同金属盐条件下合成了{[M3(pyta)2(H2O)8]·4H2O}n(M=Co(1), Ni(2),H3pyta=2,4,6-吡啶三酸)配位聚合物。X射线单晶衍射测试分析表明2个配合物是异质同晶结构,属于单斜晶系,P21/c空间群。磁性测试表明在配合物的中心离子M(Ⅱ)之间存在反铁磁耦合作用。 |

Abstract: The title coordination polymers of {[M3(pyta)2(H2O)8]·4H2O}n(M=Co(1), Ni(2)) based on H3pyta (H3pyta=pyridine-2,4,6-tricarboxylic acid) had been synthesized under hydrothermal synthesis conditions with same temperature, molar ratio and solvent, but different metal salts. X-ray diffraction analysis shows that these two polymers are hetero-isomorphic and belong to the monoclinic system, P21/c space group. The magnetic investigation shows that polymers 1 and 2 exhibit a ferromagnetic coupling between M(Ⅱ) ions. |
