| Abstract: A tetranuclear Ln(Ⅲ)-based complex: [Dy4(dbm)4(L)6(μ3-OH)2]·CH3CN (1) (HL=5-[(4-methylbenzylidene) amino]quinolin-8-ol, Hdbm=dibenzoylmethane) was manufactured and its structure was characterized in detail. Xray diffraction analysis shows that complex 1 belongs to the monoclinic crystal system and its space group is P21/n, which contains a rhombic Dy4 core. Magnetic measurements of 1 suggest it possesses extraordinary single-molecule magnet (SMM) behavior. Its energy barrier Ueff/kB was 116.7 K, and the pre-exponential coefficient τ0=1.05×10-8 s. |
