A [MnIII3O]7+ single-molecule magnet: the anisotropy barrier enhanced by structural distortion.
A trinuclear manganese complex, [Mn 3O(Me-salox) 3(2,4'-bpy) 3(ClO 4)].0.5MeCN ( 1.0.5MeCN; Me-H 2salox = 2-hydroxyphenylethanone oxime), has been synthesized and characterized structurally as a [Mn (III) 3(mu 3-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 U eff to 37.5 K.
