摘　　要：利用水热方法,以5-氯烟酸(5-ClnicH)和菲咯啉(phen)或2,2′-联咪唑(H_2biim)分别与NiCl_2·6H_2O和ZnCl_2反应,合成了1个三维配位聚合物{[Ni(μ-5-Clnic)(μ_3-5-Clnic)(μ-H_2O)_(0.5)]·1.5H_2O}_n(1)以及3个一维链状配位聚合物[Ni(5-Clnic)(μ-5-Clnic)(H_2biim)]_n(2)、[Zn(5-Clnic)(μ-5-Clnic)(H_2biim)]_n(3)和{[Zn(5-Clnic)(μ-5-Clnic)(phen)]·2H_2O}_n(4),并对其结构、荧光和磁性质进行了研究。结构分析结果表明4个配位聚合物分别属于单斜、正交(2、3)和三斜晶系,I2/a、Pbcn(2、3)和P■空间群。配合物1具有基于双核单元的三维框架结构,而配合物2～4呈现一维链结构。这些一维链通过链间N-H…O氢键和Cl…Cl卤键作用进一步连接成了二维网络和三维超分子框架结构。研究表明,聚合物1和2中相邻Ni髤离子间存在反铁磁相互作用,配合物3和4在室温下能发出蓝色荧光。Two nickel(Ⅱ)and two zinc(Ⅱ)coordination polymers, namely {[Ni(μ-5-Clnic)(μ3-5-Clnic)(μ-H2O)0.5]· 1.5H2O}n (1),[Ni(5-Clnic)(μ-5-Clnic)(H2biim)]n (2),[Zn(5-Clnic)(μ-5-Clnic)(H2biim)]n (3) and {[Zn(5-Clnic)(μ-5- Clnic)(phen)]·2H2O}n (4), have been constructed hydrothermally using 5-ClnicH (5-ClnicH=5-chloronicotinic acid), phen (phen=1,10-phenanthroline), H2biim (H2biim=2,2′-biimidazole), and nickel or zinc chlorides. Single-crystal X-ray diffraction analyses revealed that four polymers crystallize in the monoclinic, orthorhombic (2, 3) or P1 triclinic systems, space groups I2/a, Pbcn (2, 3) or P1. Polymer 1 possesses a 3D metal-organic framework based on dinuclear units. Polymers 2~4 show 1D chains, which are further extended into a 2D supramolecular network or 3D supramolecular framework through N-H…O hydrogen bonds or Cl…Cl interactions. Magnetic and luminescent properties of all compounds have been studied. CCDC: 1859598, 1;1859599, 2;1859600, 3;1859601, 4.
