The pentagonal bipyramidal single‐ion magnets (SIMs) are among the most attractive prototypes of high‐performance single‐molecule magnets (SMMs). Here, a fluorescence‐active phosphine oxide ligand CyPh 2 PO (=cyclohexyl(diphenyl)phosphine oxide) was introduced into [Dy(CyPh 2 PO) 2 (H 2 O) 5 ]Br 3 ⋅2 (CyPh 2 PO)⋅EtOH⋅3 H 2 O, and combined dynamic magnetic measurement, optical characterization, ab initio calculation, and magneto‐optical correlation of this high‐performance pseudo‐ D 5 h Dy III SIM with large U eff (508(2) K) and high magnetic hysteresis temperature (19 K) were performed. This work provides a deeper insight into the rational design of promising molecular magnets.
