Abstract: The new one-dimensional Pb(Ⅱ) coordination polymer [Pb(QOA)2]n (QOA=8-quinolinyloxyacetate anion) was synthesized by hydrothermal method, and its structure is characterized by IR, elemental analysis and single crystal X-ray diffraction analysis. The crystal belongs to monoclinic system and space group C2/c with unit cell parameters a=2.113 2(2) nm, b=1.189 86(7) nm, c=0.790 73(2) nm, β=99.081(3)°, V=1.963 3(4) nm3, Z=4. Solid UV-Vis-NIR diffuse reflectance spectra results suggest the complex has the potential semiconductor property. The solid fluorescence spectra results exhibit the complex has good fluorescence property. CCDC: 939269. |
