英文摘要	five dinuclear lanthanide complexes with formula [ln(2)l(2)(oac)(4)(meoh)(a)(h2o)(b)]center dot cmeoh center dot dh(2)o (a = 2, b = 0, c = 2, d = 0, ln = sm (1), gd (2), dy (3); a = 0, b = 2, c = 4, d = 2, ln = tm (4)) and [yb2l2(oac)(4)(meoh)(2)]center dot[yb2l2(oac)(4)(h2o)(2)]center dot 2h(2)o (5) (hl = (e)-n'-(2-hydroxybenzylidene)-2-mercaptonicotinohydrazide), have been synthesized and their crystal structures and magnetic properties are reported. all five complexes are centrosymmetric, showing a similar dinuclear core with two lanthanide ions in each complex being bridged by acetate groups in the eta(1):eta(2):mu(2) mode. the various coordination modes of acetate groups result in two kinds of coordination geometries for ln ions with the ones in complexes 1-4 and the yb2 in 5 being nine-coordinated with a mono-capped square antiprism geometry, while the yb1 ions in the other part of complex 5 are eight-coordinated with a triangular dodecahedron geometry. magnetic susceptibility studies reveal that complex 3 shows single molecule magnet behaviour with an energy barrier of 39.1 k. in addition, comparison of the structural parameters among the similar dy-2 smms with a eta(1):eta(2): mu(2) coordination mode of carboxylate groups reveals the significant role played by coordination geometry in modulating the relaxation dynamics of smms.
