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=0.93759(1) nm, b=1.11083(1) nm, c= 0.92100 (2) nm, Z=2, μ=2.919 mm-1, R1=0.0390, wR2=0.0994. 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.

A novel complex [Cd2(phen)4(fca)2](ClO4)2(H2O)2 (fca = dianion of 3-ferrocenyl- 2-crotonic acid, phen = 1,10-phenanthroline) has been synthesized and characterized by X-ray single-crystal structure analysis. It crystallizes in triclinic system, space group P?with a = 11.6297(5), b = 12.5165(5), c = 13.8986(6) ? a = 63.345(1), b = 87.747(1), g = 71.862(1), V = 1706.20(1) ?, Z = 1, Dc = 1.673 g/cm3, F(000) = 868 and m(MoKa) = 1.185 mm-1 (l = 0.71073 ). R = 0.0800 and wR = 0.1793 for 7653 observed reflections (I > 2s(I)). The structure consists of a dinuclear cation [Cd2(phen)4(fca)2]2+, two discrete perchlorate anions and two water molecules. The cationic part of the complex shows a tetrametallic core in which two fca groups act as the (O, O) bridging ligands between two cadmium(Ⅱ) ions with a distorted octahedral environment. The Cd…Cd intradimer distance is 4.128 ? 展开更多
