一维链状锌配位聚合物[Zn(Pyphen)(PZDC)(H2O)]的水热合成、结构与荧光性质

The title coordination polymer, [Zn(Pyphen)(PZDC)(H2O)] (1) (Pyphen=pyrazino [2,3-f][1,10]phen-anthroline and H2PZDC=pyrazine-2,3-dicarboxylic acid) has been obtained by using hydrothermal synthesis andcharacterized by elemental analysis, IR, TG, fluorescence spectrum and X-ray diffraction single-crystal structureanalysis. The crystal is of triclinic, space group P1 with a=0.681 8(14) nm, b=0.743 9(15) nm, c=1.759 8(35) nm,α=94.329(30)°,β=95.514(30)°,γ=97.043(3)°,V=0.878 2(3)nm3,Z=2,Mr=481.73,Dc=1.822 g·cm-2,μ=1.452 mm-1,F(000)=448, Rint=0.033 9, R=0.042 5, wR=0.090 7. In complex 1, PZDC ligands link the Zn(Ⅱ) ions to form 1Dchain structures, and further extended into a 3D supramolecular framework through π-π interactions andhydrogen bonding interactions. In addition, complex 1 exhibits strong photoluminescence at room temperature.
