Abstract: 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 and characterized by elemental analysis, IR, TG, fluorescence spectrum and X-ray diffraction single-crystal structure analysis. 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-3, 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 1D chain structures, and further extended into a 3D supramolecular framework through π-π interactions and hydrogen bonding interactions. In addition, complex 1 exhibits strong photoluminescence at room temperature. CCDC: 649569. |
