Résumé
We report here two dysprosium complexes based on phenoxidebased emissive ligands 1-(2,4-dimetylphenylazo)-2-naphtholate (L1) and anthracenolate (L2). While 1 is a dinuclear homoleptic complex [Dy 2 (L1) 6 ]•2C 7 H 8 exhibiting a zero-field slow relaxation of the magnetization, 2 is a mononuclear complex [Dy(L2) 3 (py) 3 ] (py = pyridine) showing a field-induced relaxation.
