摘要: 以1-丁基-3-甲基咪唑氟硼酸盐为溶剂, 在离子液热条件下得到两个化合物Zn3(BDC)3(MIA)2(1) 和Zn(HBTZ)(MIA)(BPY)(2). X射线衍射分析表明, 两种化合物的晶体分别属于单斜晶系, C2/c空间群和正交晶系, Fdd2空间群. 化合物1为三维结构, 在除去端基的N-甲基咪唑后, 形成了大约0.9 nm×0.9 nm的一维菱形孔道. 化合物2中的链状次级结构单元则通过π键和氢键作用形成了超分子结构.

Abstract: Two compounds, Zn3(BDC)3(MIA)2(1) and Zn(HBTC)(MIA)(BPY)(2)(BDC=terephthalic, MIA=N-methyl-imidazole, BTC=benzene-1,3,5-tricarboxylic, BPY=4,4’-bipyridine), were synthesized successfully in ionic liquids. X-ray diffraction analyses reveal that they crystallize in the monoclinic C2/c(1) and orthorhombic Fdd2(2) space group, respectively. Compound 1 exhibits a three-dimensional framework, and contains 0.9 nm×0.9 nm rhombic channels after the terminal coordinated N-methyl-imidazole removed. Compound 2 represents a supermolecule structure constructed through H bond and π…π interactions.

Key words: Ionothermal synthesis, Meltal-organic framework, Crystal structure
