Two mononuclear DyIII complexes [Dy(H2TEG)(NO3)3]·[18-crown-6] (H2TEG = triethylene glycol) (1) and [Dy(H2TEG)Cl3]·[18-crown-6] (2) have been prepared using H2TEG as ligands. Magnetic studies revealed that both complexes show field-induced double magneticrelaxation behavior with energy barriers of 28 K and 54 K. Distinct magnetic dynamic properties observed in 1 and 2 are mostly attributed to the dissimilar
