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.
