中文摘要：

在溶剂热条件下,利用Cd（II）、Ni（II）在混配体体系下合成出2个结构新颖的金属有机骨架化合物[Cd（bmimb）（idphate）]（1）,[Ni2（bibp）3（idphate）2（H2O）4]·8H2O{H2bmimb=1,4-二[（2-二甲基咪唑）亚甲基]苯,H2bibp=3,5-二甲基-1,4-二咪唑,idphate=5-氨基-2,4,6-三碘基间苯二甲酸}（2）,并通过单晶X射线衍射、红外光谱、热重分析等对这两种化合物进行了表征。结果表明,化合物（1）中,idphate采用双齿螯合的配位模式,bmimb分子采用桥连配位模式,与金属Cd连接形成三维超分子骨架;化合物（2）中,idphate只有一个羧酸基团采用了单齿配位的模式,另外一个羧酸基团悬挂在二维层外未参与配位,二维层通过分子间的弱作用连接的三维有序晶态结构。另外对化合物（1）的进行了荧光光谱分析,该化合物表现出良好的荧光性质。

英文摘要：

Two novel metal-organic frameworks, formulaed as [ Cd （ bmimb ） （idphate ） ] ① and [Ni2（ bibp）3 （idphate）2（ H20）4 ] .8H20 ②丨 H2bmimb = 1, 4 -bis [ （2-metliyl-lH-imidazol-l-yl） methyl] benzene, H2bibp = 3,5-dimethyl-1,4-biimidazole, idphate = 5-amino-2,4,6-triiodoisophthalic acid } , were synthesized by self-assembly of mixed ligands with Cd（II） and Ni（II） under solvothermal conditions and characterized by means of single-crystal X-ray diffraction, X-ray powder diffraction, infrared spectra, thermogravimetric analysis and fluo-rescence spectra. Single-crystal X-ray diffraction analysis revealed that compound （I） possess 3D supramolecular framework, in which the Cd^2 ＋ ions are linked by idphate and bmimb ligands via chelation and bridging coordination modes, respectively. In compound （2）, one carboxylic group of the idphate ligand adopts monodentate coordination mode and the other carboxylic group dangling out of the 2D layer. The adjacent layers are held together to form a 3D framework via weak interaction between different molecules. In addition, luminescence properties of compound ① in the solid state were characterized.
