摘要：To conclude the design principle for high-performance erbium-based single-ion magnets (SIMs), two half-sandwich type erbium complexes 1Er [(LOMe)Er(COT)] (LOMe = [(eta(5)-C5H5)Co{P(O)(OMe)(2)}(3)], COT = cyclooctatetraenyl) and 2Er [(THF)(2)(OAr)Er(COT)] (Ar = 2,6-Dipp(2)C(6)H(3), Dipp = 2,6-diisopropylphenyl) were synthesized, and structurally and magnetically characterized. Both of them exhibited SIM behavior. Their magnetic relaxation behaviours were further elucidated by ab initio calculations and near-IR emission spectroscopy. The results demonstrated that an axial ligand with a weaker electron-donating effect was preferential to construct high blocking barrier erbium-based SIMs.
