Synthesis, Structure And Properties Of Metal Complexes Based On Hydrazine Hydrazine And Carboxylic Acid Mixed Ligand

The coordinationpolymers (CPs) synthesized by mix-ligand(N-containing ligand and carboxylate) has been attractive recently not only the intriguing and fascinating structure, but also the potential applications as functional materials in many research field. In this paper,we using bpdb ligand and different dicarboxylate to react with transition metals in hydrothermal method, a series of novel complexes including from1D to3D topology structure has been obtained. We characterized the structure by single crystal X-ray analysis, elemental analysis and IR spectroscopy. Then we study the thermal stability,photoluminescence properties and magnetic properties of patial complexes. Finally,we also discussed the reaction conditions and the factors influencing the synthesis and structure of complexes.The work of this thesis were designed and synthesized nine transition metal complexes, of which six novel3D architecture complexes,a two-dimension net-work and two isomorphic1D chain complexes.The thermosgravimetric tests explain the complexes possess good thermal stability. Photoluminescence test indicates the emissions of complexes mainly be attribute to the π*→πc transitions of bpdb ligands. Complex3reveals antiferromagnetic interaction between Co(Ⅱ) ions.
