| As a novel microporous materials, MOFs have the application inporous material, such as gas storage, separation, catalysis, further more,they characteristic can be adjust by directional select of metal ions andorganic ligand, so they were more and more applied in photology,electrology, magnetical, chiral resolution.In this paper, through benzene-1,3,5-tricarboxylic acid,benzene-1,2,4,5-tricarboxylic acid, transition metal and rare-earth metalsynthesized14novel polynuclear complexes. They are characterized byX-ray diffraction, elemental analysis, infrared analysis,thermogravimetric analysis. Then, we take systematic study of theirstructure and properties.1. Six transition metal polynuclear complexes were synthesized byusing the benzene-1,3,5-tricarboxylic acid ligands. They are[Co2Na4（btc）3（H2O）14]·3H2O，[Pb3（btc）2（H2O）4]·H2O,[Co3（btc）2（H2O）3],[Mn（Hbtc）]（CH3NH2），[Fe（btc）（HCO2）（DMF）]， and[ZnNa2（Hbtc）（H-2O）4]·2H2O.2.[Dy3（Hbtc）2（oba）2（2,2’-dpa）]，and [La3（Hbtc）3（oba）2（2,2’-dpa）]（Cl-）were synthesized by the rare-earth metal and thebenzene-1,3,5-tricarboxylic acid, oba,2,2’-dpa ligands. 3. Three rare-earth metal polynuclear complexes were synthesizedby using the benzene-1,2,4,5-tricarboxylic acid ligands. They are[Er2（btec）1.5（H2O）4]·3H2O,[Y2（btec）1.5（H2O）4]·4H2O,[Dy2（btec）1.5（H2O）4]·3H2O, which have the1D filled microchannelstructure and water clusters coordination polymers.4.Three kinds of simple novel complexes,[ZnNa2（pdc）2（H2O）8]·2H2O， Zn2（2,2’-dpa）2（1,10’-phen）2（H2O）2andFe（3-pyra）2（H2O）2，were synthesized by using the nitrogen containingheterocyclic ligands. |
