Syntheses And Crystal Structure Of Pyrazinamide And Benzimidazole Ligands And Their Metal Complexes

The coordination polymer with organic ligands and inorganic metal salt ligand synthesis, so both the dual characteristics. Coordination polymer in fluorescence, magnetic and electrical showed excellent properties of the metal complexes of synthesis, structure, properties, research by chemists to more and more attention, its application is becoming more and more widely, has broad space for development.Paper to pyrazinamide, benzene and imidazoles organic ligands, Using a variety of synthetic methods, and metal ion of Co, Cu ion respectively, design three kinds of metal coordination polymer was synthesized, and the structure of the three kinds of metal coordination polymer were determined and characterized, Enriched the type of transition metal coordination polymer database.The main work of this paper is as follows:1, the use of pyrazinamide and pyridine-2-formaldehyde synthesis ligand [N’-((pyridine-2-) methylene) pyrazine-2-kappa hydrazine] and Cu(BF4)2·6H2O by the hydrothermal method with a one dimensional helical polymer was synthesized by P-Cu.2, pyrazine-2-formic acid and benzene and imidazole as the starting material, through a number of steps to get ligand L1;Ligand was synthesized by the method of natural volatile solvent L1 with transition metal ions Co(II) coordination polymer L1-Co;4-imidazole to o-phenylendiamine with formaldehyde as raw material, condensation get schiff base intermediate first, and then to schiff alkali n-cyclohexylmaleimide reaction, finally get ligand Bim oxidative dehydrogenation, ligand was synthesized by the method of natural volatile solvent Bim with transition metal ions Cu(II) coordination polymer Bim-Cu.Their structure was analyzed, to get the test data are analyzed.
