| Abstract: | A new family of mononuclear lanthanide complexes with formula [LnIII(L)Cl3] (Ln = Eu (1), Tb (2), Dy (3), Er (4), Yb (5)) and L = N,N0-bis((1,2-diphenyl-(pyridine-2-yl)methylene)-(R,R/S,S)-ethane-1,2-diamine has been obtained employing enantiomerically pure Schiff bases. The complexes have been structurally characterized using X-ray single crystal and powder diffraction. Their dynamic magnetic properties have been studied showing that this family presents slow relaxation of the magnetization under certain conditions and confirms the different behavior of each LnIII cations in isostructural complexes: only the Er one possibly relaxing via an overbarrier Orbach process, while Raman process dominates for Dy and Yb derivative. |
