利用水热合成法,以金属盐NiSO4·6H2O与三脚架配体1,3,5-三(1-咪唑基)苯(tib)进行组装,得到了一个结构新颖的有序金属-有机框架(MOFs){[Ni3(tib)2(H2O)12](SO4)3}n(1).利用X-射线单晶衍射仪检测其晶体结构,并进行元素分析,红外光谱射线,粉末衍射等相关表征.配合物1为一个典型的(6,3)拓扑二维蜂窝网结构,由于π-π空间叠加效应和氢键相互作用形成了稳定的三维结构.对配合物1介电性能进行测定,发现其在138℃时达到最大的介电异常值10.08,为典型的介电材料,通过热重分析,表明此材料具有较好的热力学稳定性,对新型多维MOFs及新型介电性能材料的开发具有借鉴和指导意义.

The new novel metal-organic framework (MOFs){[Ni3(tib)2(H2O)12](SO4)3}n(1) is obtained by hydrothermal reaction of the metal salt NiSO4·6H2O and the three-connecting ligand 1,3,5-tris(1-imidazolyl) benzene (tib). The crystal data and structure are established by single-crystal X-ray diffraction analysis, and characterized by elemental, IR, XRD, et al. and by using SHELXL-97 software for the structure elucidation and Topos40 software for its topology analysis. It shows that complex 1 is a 2D network honeycomb networks with (6,3) topology, which is further linked to three-dimensional (3D) frameworks by the spatial additive effect of π-π and interaction of hydrogen bonds. Dielectric constant studies show that the εmax of complex 1 reaches a value of about 10.08 at 138 ℃, which is the typical dielectric material. This material has good thermal stability indicated by thermogravimetric, which provides a reference and guidance for the development of the novel multidimensional MOFS and dielectric properties of new materials.
