The novel Zn Ⅱ 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, β3=107.808(1)°, a=0.937 59(1) nm, b=l.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
