Five new dysprosium complexes were synthesized and characterized: neutral Dy(NCS) 3 · 6(H 2 O) ( 1 ), [Dy(NCS) 3 (H 2 O)(bpy) 2 ] · 0.5(bpy) · H 2 O ( 2 ), and [Dy(NCS) 3 (H 2 O)(phen) 2 ] · phen · 0.5H 2 O ( 3 ), as well as ionic [Hbpy][Dy(NCS) 4 (bpy) 2 ] · H 2 O ( 4 ) and [Hphen][Dy(NCS) 4 (phen) 2 ] ( 5 ). In all complexes, the metal coordination number (CN) is 8. All complexes exhibit single‐ion magnet behavior. The influence of the structural features on Δ E/k B values is discussed. The thermal behavior of the new compounds was studied under an inert atmosphere in the temperature range of 30–550 °C. The thermal stability of the complexes is determined by the presence of solvate molecules.
