A bent dysprosium bis(amide) single-molecule magnet (SMM) has been successfully synthesized and characterized. The compound, [Dy(N(SiPr3)2)2][Al(OC(CF3)3)4] (1-Dy), was isolated along with its diamagnetic yttrium analogue, 1-Y. The study aimed to explore the magnetic properties of this complex, which was predicted to have a high energy barrier to magnetic reversal (Ueff) of up to 2600 K, significantly higher than previously reported values for dysprosium SMMs. However, experimental results showed a lower Ueff of 950 ± 30 K for 1-Dy, indicating that the predicted high barrier was not fully realized. Ab initio calculations suggested that the bent geometry of the complex leads to significant magnetic anisotropy, but magnetic relaxation is faster than expected due to enhanced spin-phonon coupling from the flexible coordination sphere. The study also highlights the importance of molecular rigidity in controlling spin-phonon relaxation in SMMs. The magnetic properties of 1-Dy were investigated using various techniques, including dc and ac susceptibility measurements, which revealed that the complex exhibits SMM behavior with a relatively low Ueff. The results suggest that the flexible coordination environment in 1-Dy enables rapid magnetic relaxation, which may limit its effectiveness as a high-temperature SMM. The study provides insights into the factors influencing the magnetic properties of dysprosium-based SMMs and the challenges in synthesizing and characterizing such complexes.A bent dysprosium bis(amide) single-molecule magnet (SMM) has been successfully synthesized and characterized.
