2010302010185 ; 化學系 ; Tetranuclear cubic complexes of [Co-4(heiP)(4)(MeOH)(4)] (1) and [Co-4(heiP)(4)(nit-p-py)(4)] (2) (H(2)heip = 1,1,1,5,5,5-hexafluoro-4-[(2-hydroxyethyl)imino]-2-pentanone and nit-p-py = 2-(p-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) were prepared. Complexes 1 and 2 have alkoxo-bridged cubic core structures. Magnetic susceptibility measurements revealed the occurrence of ferromagnetic interactions among Co-II ions in 1, while antiferromagnetic interactions were operative in 2.
