The first dysprosium complexes with a terminal fluoride ligand are obtained as air-stable compounds. The strong, highly electrostatic dysprosium-fluoride bond generates a large axial crystal-field splitting of the J=15/2 ground state, as evidenced by high-resolution luminescence spectroscopy and correlated with the single-molecule magnet behavior through experimental magnetic susceptibility data and ab initio calculations.
首次获得了具有端基氟配体的镝配合物，它们是稳定的空气稳定化合物。强的、高度静电的镝-氟键产生了 J=15/2 基态的大轴向晶体场分裂，这一点通过高分辨率发光光谱得到证实，并通过实验磁化率数据和从头算计算与单分子磁体行为相关联。
