cqvip:A new coordination polymer associated with zinc ion,[Zn(Tda)(bpp)] n (1,H 2 tda=thiophene-2,5-dicarboxylic acid,bpp=1,3-bis(4-pyridyl)propane),was prepared under solvothermal conditions,and characterized by single-crystal X-ray diffraction,elemental analysis and IR spectra.The complex belongs to monoclinic,space group P2 1 /c with a=9.8799(4),b=12.0430(6),c=15.4269(9),β=95.424(5) o,V=1827.33(16) 3,Z=4,D c=1.577 g/cm 3,S=1.074,μ=1.486 mm-1,F(000)=888,M r=433.80,R=0.0359 and wR=0.0968 for 2685 observed reflections (I > 2σ(Ⅰ)).Complex 1 displays an interesting 2D lattice structure.In 1,four coordinated zinc ions were bridged by Tda and bpp ligands to generate a (4,4) two-dimensional layer.The thermogravimetric analysis,powder X-ray diffraction (XRD) and luminescent properties for 1 also have been explored.
