| 摘要 | Eight dinuclear lanthanide complexes of compositions [Pr2L2(NO3)(4)(H2O)]center dot EtOH (1), [Nd2L2(NO3)(4)(CH3CN)]center dot CH3CN (2), [Sm2L2(NO3)(4)(CH3CN)]center dot CH3CN (3), [Eu2L2(NO3)(4)(H2O)] (4), [Tb2L2(NO3)(4)] (5), [Dy2L2(NO3)(4)] (6), [Ho2L2(NO3)(4)] (7) and [Er2L2(NO3)(4)] (8) (HL = 2-{[(2-hydroxy-3-methoxybenzyl)imino]methyl}quinoline-2-formaldehyde) have been synthesized by reactions of Ln(NO3)(3)center dot 6H(2)O with a tetradentate quinoline-based Schiff base ligand (HL) in MeCN/EtOH/NEt3 solution. The structures of 1-8 are characterized by X-ray single crystal diffraction analysis. They exhibit four distinct structures. In complex 1, two Pr-III atoms are triply bridged by three oxygen atoms, including an unusual water bridge. Complexes 2 and 3 are isostructural, in which two metal centres are nine- and ten-coordinated, respectively. There are two characteristic Eu-III ions in 4, which are eight- and ten-coordinated, respectively. In the isomorphous compounds 5-8, the two Ln(III) atoms in the centrosymmetric molecules are doubly bridged by phenolate oxygen atoms and both metal ions possess nine-coordinate environments. Dc magnetic susceptibility studies in the 2-300 K range were performed for compounds 6 and 7. Antiferromagnetic interactions were determined for these two complexes. Complex 6 shows slow magnetic relaxation behaviour with an energy barrier (U-eff/K-B) of 14.3 K. |
