【Abstract】 The aim of this thesis is to construct a series of coordination polymers with various structures based on several isomers of multidentate N-donor ligands1-((1H-1,2,4-triazol-1-y1)methy1)-3,5-bis(pyridy1)-1,2,-triazole (tmbpt), polycarboxylates/polyoxometalates anions and transition metal ions under hydrothermal conditions. The synthesis conditions, types of topological structures, effects of the structures of organic ligands and the types of metal ions and anions on the structures of the compounds, and the relationship between structures and properties of the compounds have been investigated in detail.Twenty-six coordination polymers have been hydrothermally synthesized and characterized by infrared spectra (IR), elemental analyses and thermogravimetric (TG) analyses. Moreover, the luminescent properties and photocatalytic behaviors of the compounds have also been investigated.1.
