A trinuclear manganese complex, [Mn3O(Me-salox) 3(2,4′-bpy)3-(ClO4)]· 0.5MeCN (1·0.5MeCN; Me-H2salox = 2-hydroxyphenylethanone oxime), has been synthesized and characterized structurally as a [MnIII 3(μ3-O)]7+ core. Structural distortion by the twisting of the oxime ligand dominates ferromagnetic interactions within three Mn ions to give an S = 6 ground state as well as to enhance the anisotropy barrier Ueff to 37.5 K. ? 2008 American Chemical Society.
