Abstract：

Three　six-coordinate　DyIII　single-molecule　magnets　(SMMs)　[Dy(OtBu)2(L)4]+　with　local　D4h　symmetry　are　obtained　by　optimizing　the　equatorial　ligands.　One　of　the　compounds　with　L=4-phenylpyridine　shows　an　energy　barrier　(Ueff)　of　2075(11)　K,　which　is　the　third　largest　Ueff,　and　the　first　Ueff＞2000　K　for　SMMs　with　axial-type　symmetry　so　far.　Ab　initio　analysis　indicates　that　the　exceptional　uniaxial　magnetic　anisotropy　is　deeply　related　to　the　axially　compressed　octahedral　geometry.　This　work　provides　a　new　insight　into　the　local　D4h　symmetry　for　high-performance　SMMs.　©　2020　Wiley-VCH　GmbH
