摘　　要：A\} novel two-dimensional coordination polymer Zn 3(PTC) 2(H 2O) 8·4H 2O was formed by \{Zn(CH 3COO) 2·\}2H 2O and 2-pyridine-1,3,5-tricarboxylate(H 3PTC) under the hydrothermal condition at 417 K and characterized by fluorescence. The crystal structure of the compound was determined by single-crystal X-ray diffraction analyses. The six-coordinated Zinc(Ⅱ) center displays an octahedral geometry . The crystal is monoclinic and space group is P2(1)/c with a=0.722 70(14) nm, b= 1.866 7(4) nm , \{c=\}1.072 6(3) nm, α=90°, β=103.198(19)°, γ=90°, V=1.408 7(6) nm 3, Z=4, D c= 2.474 Mg/m 3, M r=828.536, μ=3.099 mm -1 , F(000)=1 060, GOF=0.892, R=0.061 3, wR= 0.133 9 .A\} novel two-dimensional coordination polymer Zn 3(PTC) 2(H 2O) 8·4H 2O was formed by \{Zn(CH 3COO) 2·\}2H 2O and 2-pyridine-1,3,5-tricarboxylate(H 3PTC) under the hydrothermal condition at 417 K and characterized by fluorescence.
