Abstract

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 [Mn^III 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 U_eff to 37.5 K.
