Résumé:
This work has been devoted to the synthesis of new copper-based hybrid materials and organic matrices based on oxygen and nitrogen ligands. The structural study and physiochemical characterization of these compounds was carried out using two techniques, namely single crystal Xray diffraction and differential thermal analysis. The synthesis by aqueous method permits the characterization of several new structures based on copper with different organic matrices. These include:
-Four products based on (2-hydroxy-1-naphthaldehyde with nitrogen ligands (2,2 'bipyridine) , (4-dimethylaminopyridine) and (1,10-phenanthroline).
- Four nitrogen-based compounds (4-dimethylaminepyridine, 2-aminobenzamide, 2,2'-bipyridine). - Two Schiff bases derived from the condensation of 4-nitrobenzenamine and 3-aminopyridine with 2-hydroxy-1-naphthaldehyde.The ligand [(C9H8NO) + (HSO4) -. H2O] was also synthesized. The study of hydrogen bonds based on Bernstein's theory, allowed understanding the cohesion of molecules in the crystal.
