Nouveaux ligands hétérocycliques et leurs complexes métalliques : étude des propriétés magnétiques

Abstract : Fistly, new nitrogen heterocycles containing 1,2,4-triazine units have been prepared: btrz, cpytrz, pytrz, bpy-pytrz et pytrz. Then, their complexation behaviour have been studied with d10 transition metal ions (CuI, AgI, ZnII) by UV-Vis, Nuclear Magnetic Resonance, ESI-MS and X-ray diffraction spectrometries. Particularly, the bpy-pytrz ligand CuI complex gave a dinuclear double-strand helicate, of which H-H (Head to Head) or H-T (Head to Tail) conformation will be determined by X-ray diffraction. Elsewere, for the first time we were able to obtained suitable single crystals of the Uranium (UO2(NO3)2) complex with bpy-pytrz ligand. Secondly, the synthesis of sequential 2-oxapropylene-bridged bipyridine-bisdiazine strands (bpy-bpz, bpy-bpm, bpy-btz2,2', bpy-btz4,4') has been reported. Their complexation behaviour with 3dn transition metal ions (CoII, NiII, CuII) have been studied in solution and in solid phases. Finally, preliminary interesting results have been achieved on the magnetic properties of their complexes and concerned particularly the dinuclear NiII neutral complexes.
