Two coordination polymers, [ML2]n （M = Co （1）, Ni （2）, L = 3-aminobenzoic acid anion）, were synthesized by hydrothermal reaction, and their crystal structures were determined by X-ray diffraction analysis. Both compounds crystallize in monoclinic, space group P21/n with a = 8.8029（8）, b = 4.5297（4）, c = 15.2002（14）A°, β= 105.6280（10）°, C14H12CoN2O4, Mr= 331.19, Z= 2, V = 583.69（9）A°^3 Dc= 1.884 g/cm^3,μ=1.490 mm^-1, F（000） = 338, R = 0.0234 and wR = 0.0679 for 1337 observed reflections （I 〉 2σ（I）） for 1, and a = 8.7501（7）, b = 4.5191（4）, c = 15.1448（12） A°,β = 105.7730（10）° C14H12 NiN2O4, Mr = 330.97, Z = 2, V = 576.31（8）A°3, Dc = 1.907 g/cm^3,μ = 1.703 mm^-1, F（000） = 340, R = 0.0206 and wR = 0.0572 for 1209 observed reflections （I 〉 2σ（I）） for 2. In the title complexes, the M （Ⅱ） ion presents an octahedral geometry with four oxygen donors in the equatorial positions and two nitrogen donors in the axial positions. Each of the complexes has a two-dimensional network structure that is formed by the bridging of the ligand in a μ3-bridging mode via its amino and carboxyl groups.
Complexes { [Ln（H20）2（TsGlyH）a]m·nH2O}∞ （Ln=La （1）, m=2, n=6; Nd （2）, m=2, n=7; Eu （3）, m=2, n= 0; Gd （4）, m=2, n=2; Er （5）, m=3, n=5 and Yb （6）, m=3, n=0, TsGlyH=N-p-tosylglycine monoanion）, have been prepared and characterized by IR spectra, elemental analysis, and TG-DTG 4 and 5 were structurally determined by X-ray diffraction analysis, showing that both of them are comprised of a one dimensional chain structure established via the coordination of μ-carboxylate groups from N-p-tosylglycinate to the corresponding lanthanide（Ⅲ） ions. The one dimensional chains were found inclined to form two-dimensional network via hydrogen bonding and then three dimensional network structure via non-classical hydrogen bonding. The fluorescence spectra of them revealed that the fluorescence of the ligand was quenched by Ln（Ⅲ） ions. In the tested biological activity experiments, they behaved inhibiting effects against the growth of bacteria, indicating that it is a potential medicament worthy of further investigation.
A one-dimensional double-chain coordination polymer [Mn(phen)(tsgluo)] was synthesized in a mixed solution and its crystal structure was determined by X-ray diffraction method. It crystallizes in orthorhombic system with space group P212121. The crystal data are: a=0.530 78(17) nm, b=1.723 9(5) nm, c=2.456 9(8) nm, Z=4, μ=0.729 mm-1, Dc=1.579 g·cm-3, V=2.248 1(12) nm3, R1=0.033 1, ωR2=0.078 9. In the title complex, each Mn(Ⅱ) ion presents a octahedral geometry with the coordination of two nitrogen atoms from 1,10-phenanthroline and four oxygen atoms from three different tsgluo2- ligands. The γ-carboxyl coordinates to Mn(Ⅱ) in the mode of bidentate chelate, while the α-carboxyl coordinates in a bidentate bridging mode. CCDC: 253910.
Two new ternary complexes [Zη（3-aba）2（phen）]·2.58H2O 1 and {[Cd（3-aba）- （phen）2]·（NO3）·（1.5H2O） }n 2 （3-aba = 3-aminobenzoic acid anion, phen = 1,10-phenanthroline） were synthesized and characterized by elemental analysis, IR, UV spectrum and X-ray diffraction. Complex 1 crystallizes in the rhombohedral system, space group R3 with a = 3.5733（3）, b = 3.5733（3）, c = 1.1231（2） nm; V= 12.419（3） nm^3, C26H25.17NaO6.58Zn, Mr= 564.37, Z= 18, F（000） = 5253, μ= 0.937 mm^-1, Dc = 1.358 g/cm^3, R = 0.0668 and wR = 0.1690 for 2424 observed reflections （I〉 2σ（I））. Complex 2 belongs to the tetragonal system, space group P4/ncc with a = 2.88451（10）, b = 2.88451（10）, c = 1.55571（11） nm, V= 12.9441（11） nm^3, C31H25CdN6O6.50, Mr = 697.97, Z = 16, F（000） = 5648,μ=0.727 mm^-1, Dc= 1.433 g/cm^3, R = 0.0607 and wR = 0.1742 for 3468 observed reflections （I 〉 2σ（I））. Complex 1 displays a mononuclear structure. The carboxylate group of 3-aminobenzoic acid anion coordinates to Zn（Ⅱ） in a chelating bidentate mode, and the nitrogen atom of the ligand does not involve in coordination. Complex 2 exhibits a one-dimensional chain structure with 3-aminobenzoic acid anion coordinating to Cd（Ⅱ） in a μ2-bridging mode through its nitrogen atom and one of its oxygen atoms.
