摘　　要：利用6-hydroxy-2-naphthoic acid(HNA)作为羧酸配体,N,N'-bis(3-pyridinecarboxamide)-1,6-hexane(L)作为N-质子配体,在水热条件下共同与Zn(II)离子进行配位自组装,从而得到了一个配合物,[Zn2(H2O)L2(HNA)4]·2H2O(1).结构分析发现,配合物1的结构是三维超分子的.结构中,配体L,HNA和Zn(II)离子三者配位结合,形成了一个一维的链状结构.氢键作用将两条这样的链聚合,得到了一个相互缠结的双链结构.随后,氢键作用又将这些双链拓展成为三维的超分子结构.此外,我们还研究了配合物1的固态荧光性能.The self-assembly of 6-hydroxy-2-naphthoic acid(HNA)as carboxylate ligand,N,N’-bis(3-pyridinecarboxamide)-1,6-hexane(L)as N-donor ligand and Zn(II)ions under hydrothermal condition generated a complex,[Zn2(H2O)L2(HNA)4]·2 H2O(1).The structural analysis reveals that complex 1 is a 3D supermolecular structure containing a kind of 1D chains constructed from L ligands,HNA ligands and Zn(II)ions,and two such chains are linked each other through hydrogen bonds result in an fascinating entangled double chain.Further,these double chains are extended into a 3D supermolecular structure by hydrogen bonds.Additionally,the solid state fluorescence property of complex 1 has been investigated.
