Abstract: | A novel enneanuclear manganese complex, [Mn(9)O(4)(Mesao)(6)(MeO)(3)(O(2)CMe)(3)(OH)(MeOH)(2)]·2.5DMF [1; Me-saoH(2) = 2-hydroxyphenylethanone oxime], was synthesized. The structure of 1 contains an unusual [Mn(9)O(4)] core with an unprecedented defective "supertetrahedron" topology based on two parallel, onset stacked 9-MC-3 and 15-MC-6 metallacrown subunits. Magnetic studies indicate that 1 behaves as a single-molecule magnet. |
