摘要：
Five new dysprosium complexes were synthesized and characterized: neutral Dy(NCS)(3)center dot 6(H2O)(1), [Dy(NCS)(3)(H2O)(bpy)(2)]center dot 0.5(bpy)center dot H2O (2), and [Dy(NCS)(3)(H2O)(phen)(2)]center dot phen center dot 0.5H(2)O (3), as well as ionic [Hbpy][Dy(NCS)(4)(bpy)(2)]center dot H2O (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 Delta 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 degrees C. The thermal stability of the complexes is determined by the presence of solvate molecules.
