Synthesis, Crystal Structure, Fluorescence Property and Antibacterial Activity of Two Unprecedented One-dimensional Chain Metal organic Coordination Polymers： Zn（H-SSA）（Phen）（H20）2 and Cu（H-SSA） （Phen） （H20）2

The reaction of 5-sulfosalicylic acid(H3-SSA) with o-phenanthroline(Phen),NaOH,and Mcl2(M=Zn,Cu) affords Zn(H-SSA)(Phen)(H2O)2(1) and Cu(H-SSA)(Phen)(H2O)2 (2),respectively ,compounds 1 and 2 are characterized by elemental analysis,IR,fluorescence spectra and single crystal Xray diffraction analysis.The X-ray diffraction analyses reveal that compounds 1 and 2 are isostructure.The 5-sulfosalicylic acid ligand loses two protons at the sulfo-group and carboxylic group during the reaction.The Zn(II) and Cu(II)ions are sixcoordinated and adopt distorted octahedral geometry,which are surrounded by two N atoms from Phen,two O atoms from two water molecules,one O atom from-SO3 group and one oxygen from carboxylic group of the other H-SSA.Compounds 1 and 2 have unprecedented one-dimensional linear chain formed by a repeating mononuclear structureal unit.which is bridged by H-SSA.The fluorescence intensity of 1 and 2 is stronger than that of Phen and H3-SSA at 400nm.The lowest excited single states of these complexes are assigned as mainly Phen localized 1(π π),The antibacterial activity test shows that compounds 1 and 2 strongly inhibit the growth of Streptococcus haemolyticus,Straphylococcus aureus and Escherichia coli.

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.
