在水热条件下,利用锌离子与2种有机配体合成出1个结构新颖的金属有机骨架化合物[Zn2(BPDC)(IN)2](H2BPDC=4,4＇-联苯二羧酸；HIN=异烟酸),并通过单晶X射线衍射、红外光谱、热重分析和荧光光谱等对该化合物进行了表征。结果表明,该化合物结构中Zn离子与BPDC的羧基形成双核金属次级结构单元[Zn2(—CO2)2(IN)2],相邻次级结构单元通过IN配离子连接形成[Zn2(—CO2)2(IN)2]∞二维层面,相邻的二维层通过BPDC相互连接形成具有三重互穿的简单格子拓扑结构。该化合物表现出良好的荧光性质。%A new metal-organic framework compound, [ Zn2 ( BPDC) ( IN)2 ] ( H2BPDC=biphenyl-4,4'-dicarboxylic acid, HIN=isonicotinic acid), was synthesized by self-assembly of mixed ligands and Zn(Ⅱ) under hydrothermal conditions and characterized by means of single-crystal X-ray diffraction, X-ray powder diffraction, thermogravimetric analysis and fluorescence spectra. Single-crystal X-ray diffraction analysis re-vealed that Zn ions connected to carboxyl of BPDC, forming dual-core metal secondary building units( SBUs) [ Zn2(—CO2 ) 2( IN) 2 ] , the SBUs connected to the adjacent SBUs through IN to form an unlimited extension two-dimensional network [Zn2(—CO2)2(IN)2]∞. The adjacent [Zn2(—CO2)2(IN)2]∞ layers were inter-connected by BPDC ligand to form a simple three-dimensional framework. The three-dimensional framework of the compound has simple cubic lattice topology of threefold interpenetrating. In addition, luminescence properties of [ Zn2( BPDC) ( IN) 2 ] in the solid state were characterized.
