| 中文摘要 | two dinuclear triple-stranded helicates [ln(2)l(3)](3+) (ln = dy and tb) obtained via self-assembly from the ligand hl (2,6-diformyl-4-methylphenol di(benzoylhydrazone)) and lanthanide perchlorate have been synthesized and characterized. the crystal structural analysis demonstrates that three ligand strands wrap around a pseudo-threefold axis defined by the two metal ions, leading to a 'meso'-relation between the right-(delta) and left-hand (lambda) configurations of [ln(2)l(3)](3+) in the crystal. each ln(iii) ion is coordinated by nine donor atoms in a distorted tricapped trigonal-prismatic arrangement. alternating current (ac) susceptibility measurements of [dy(2)l(3)](3+) reveal a frequency-dependent out-of-phase signal under a 700 oe dc field, indicating the onset of the slow relaxation of magnetization with a roughly estimated activation energy of similar to 5 k and tau(0) of 10(-7) s. |
