Synthesis,Structures And Characters Of Coordinaion Polymers With 4-amino-3,5-bis(1-imidazolylmethyl)-1,2,4-triazole

The organic bridging ligand containing imidazole and triazole groups have many characteristics such as strong coordination ability, more coordination atoms, etc; their coordination polymers has good light, electricity, magnetic and catalytic properties, biological activity and the broad prospects of the function of new materials, ion-exchang and super-molecular self-assembly.In the work, we reported twelve coordination polymers using flexible ligand 4-amino-3,5-bis(1-imidazolylmethyl)-1,2,4-triazole (abit) and transition metal cations Cd(Ⅱ),Zn(Ⅱ),Mn(Ⅱ) with the hand of different types of anions(SO42-,BF4-,ClO4-,PF6-) and the second ligands(dca-, isophthalic acid, maleic acid), namely, [Cd(abit)(dca)2(H2O)2] (1) , [Cd(fum)(abit)(H2O)] (2) , [Cd(abit)(bdc)] (3) ,[Cd4(abit)(bdc)4(H2O)2] (4),[Zn(abit)(SO4)]·5H2O (5),[Zn(abit)2](BF4)2·2H2O (6),[Zn(abit)2](ClO4)2·2.5H2O (7),[Zn(fum)(abit)(H2O)] (8),{[Mn(abit)3](ClO4)2}n (9),{[Mn(abit)3](PF6)2}n (10) , [Mn(abit)(dca)2(H2O)2]n (11a)和[Mn(abit)(dca)2(H2O)2]n (11b). These compounds have been characterized by elemental analysis, IR Spectra, thermogravi-metric analysis and luminescent of part of them, their syntheses and structures are also fully described in this thesis.Through the synthesis and study of these coordination polymers, we found that the characteristics of metal ion and coordination geometry, anion types, solvent, the ratio of metal ions and ligands in the reaction systems and the second ligands and so on can affect the coordination polymer structures and properties.
