ABSTRACT: We report here a complete study of coordination of the 5-aminomethyl-[13] aneN4 ligand by three metals: Cu(II), Ni(II) and Cr(III) in order to determine the effect of the C-functionalization of the macrocycle on the stability of the metal complexes even if we change the size of the metal used. The results obtained by spectrometry, EPR and X-ray of the metal complexes showed that the copper is pentacoordinate in square-based pyramidal environment, but the chromium and nickel complexes are hexacoordinated in octahedral geometry. In all metal complexes, the coordination of the nitrogen atom is observed in the primary amine function.
