| 中文摘要 | two new dysprosium(iii) complexes, [dy-2(hl1)(4)(co3)]center dot 4h(2)o (1) and [dy-2(l-2)(2)(no3)(2)(ch3oh) (2)]center dot 4ch(3)cn (2), have been synthesized from the schiff-base ligands n'-((2-hydroxy-1-naphthyl)methylene)benzohydrazide (h2l1) and n'-((2-hydroxy-1-naphthyl) methylene) picolinohydrazide (h2l2). single-crystal x-ray diffraction studies reveal that four mono-deprotonated h2l1 ligands and two di-deprotonated h2l2 ligands which have undergone keto-enol tautomerism coordinate to the two dysprosium centres of complexes 1 and 2, respectively. the dc magnetic properties of complexes 1 and 2 are different. the phenoxido bridges in complex 1 mediate antiferromagnetic interaction between dy-iii ions, while ferromagnetic interaction was clearly observed in alkoxido-bridged dinuclear complex 2. furthermore, both complexes show frequency-dependent ac magnetic susceptibilities, indicating a slow relaxation of the magnetization, typical of smm behaviour. |
