| 英文摘要 | Six transition-metal clusters of compositions [Mn7L6](NO3)(2)center dot 2CH(3)OH (1), [Fe7L6](NO3)(2)center dot 2CH(3)OH (2), [Co7L6]-(NO3)(2)center dot 2CH(3)OH (3), [Cu7L6](NO3)(2) (4), [Zn7L6](NO3)(2)center dot 2CH(3)OH (5), and [Cu6Na2L6](NO3)(2)center dot 4CH(3)OH (6) {H2L = 2-(2-hydroxy-3-methoxybenzylideneamino)phenol} have been synthesized under solvothermal conditions. The structures of 1-6 have been established based on single-crystal X-ray diffraction studies. Complexes 1-5 possess disk-shaped {M-7(II)} cores, with the central M-II ion and the six peripheral MII ions being linked by six mu(3)-O atoms. The six MII ions of the rim of the disk are bridged in a pairwise manner by six mu(2)-O atoms. Complex 2 is a very rare example of a disk-shaped {Fe-7} cluster in which all of the Fe atoms exhibit +2 oxidation state. Furthermore, this is the first time that the five isostructural heptanuclear clusters were constructed by using an identical Schiff base ligand. The molecule of complex 6 contains a capsule-like {Cu6Na2} core. In this core, two sodium ions reside on the two vertices of the capsule and the 12 vertices of the {Cu6O6} hexagonal prism are occupied by alternately arrayed six Cu-II ions and six O atoms. Photoluminescence studies suggest strong emission for 5 in the solid state at room temperature. Variable-temperature dc magnetic susceptibility studies were carried out on polycrystalline samples of 1-4 and 6. The ac susceptibility studies were also performed with 3. Strong out-of-phase, chi'', signals were observed for 3 at zero field, suggesting that 3 is a class of single molecule magnet (SMM). |
