| Abstract: The novel ZnⅡ complex, {[Zn(TSC)(MAL)]·H2O}n
(1), where TSC is thiosemicarbazide and MAL is malonate radicle, was synthesized by self-assembling from the reaction of stoichiometric zinc chloride, thiosemicarbazide and malonic acid in solution at pH 4.5~5.0. The structural and physicochemical properties were characterized by X-ray diffraction, infrared spectroscopy, electronic spectra and thermal analysis. The crystal data for the title coordination polymer: Monoclinic,
P21/c, β=107.808(1)°, a=0.937 59(1) nm, b=1.110 83(1) nm, c=0.921 00(2) nm, Z=2, μ=2.919
mm-1, R1=0.039 0, wR2=0.099 4. The structure feature is that the bridging dicarboxylates effectively link the zinc centers to form polymeric chain in a zig-zag way, which is stabilized by N-H…O, N-H…S and O-H…O hydrogen bonds. CCDC: 231861. |
