英文摘要	A hydroxide-bridged centrosymmetric Dy-III dimer with each Dy-III being five-coordinated has been synthesized using bulky hindered phenolate ligands. Magnetic studies revealed that this compound exhibits a slow magnetic relaxation of a single-ion origin together with a step-like magnetic hysteresis of the magnetic coupled cluster. The thermal relaxation barrier of magnetization is 721 K in the absence of a static magnetic field, while the intramolecular magnetic interaction is very large among reported 4f-only dimers. CASSCF calculations with a larger active space were performed to understand the electronic structure of the compound. The thermal relaxation regime and the quantum tunneling regime are well separated, representing a good model to study the relaxation mechanism of SMMs with intramolecular Dy-Dy magnetic interactions.; NSFC [21290171, 21321001, 91422302, 21571008]; National Basic Research Program of China [2013CB933401]; SCI(E); ARTICLE; 2; 1288-1294; 8
