【摘要】 通过水热法合成了由5-氯烟酸为主配体构筑的[Co2(μ2-5-Clnic)2(μ3-5-Clnic)2(μ2-H2O)]n(1),[Co(5-Clnic)2(H2O)4]·2(5-Clnic H)(2),[Pb(μ2-5-Clnic)2(phen)]n(3),and[Cd(5-Clnic)2(phen)2]·3H2O(4)等四个金属有机超分子网络结构的配位聚合物,单晶XRD测定了晶体结构,配合物1形成交错的3D结构,配合物3形成1D梯链的拓扑结构,0D离散结构的配合物2和4进一步通过氢键分别形成了2D及3D的超分子网络结构。并对这四个化合物的热稳定性、磁性和发光性能进行了测试。
【Abstract】 Four new coordination compounds, namely [Co2(μ2-5-Clnic)2(μ3-5-Clnic)2(μ2-H2O)]n(1), [Co(5-Clnic)2(H2O)4]·2(5-Clnic H)(2), [Pb(μ2-5-Clnic)2(phen)]n(3), and [Cd(5-Clnic)2(phen)2]·3H2O(4) were generated by hydrothermal methods from the corresponding metal(Ⅱ) chlorides, 5-chloronicotinic acid(5-Clnic H) as a principal building block, and 1,10-phenanthroline(phen) as an ancillary ligand(optional). All the products 1–4 were characterized by IR spectroscopy, elemental, thermogravimetric(TGA), powder(PXRD) and single-crystal X-ray diffraction analyses. Synthetic aspects, structural features, thermal stability, magnetic(for 1) and luminescent(for 3 and 4) properties were also investigated and discussed.
