Symmetry related [DyIII6MnIII12] cores with different magnetic anisotropies†
Abstract
Two heterometallic [DyIII6MnIII12] clusters comprising of the same [MnIII8O13] fragment, four isolated MnIII ions and two linear [DyIII3] units have been synthesised. Except for the same composition, the main difference of these two cores lies in the coordination environment and the orientations of the linear [DyIII3] units. This difference leads to an alternation in the symmetry of the two cores that significantly modulates their magnetic properties including ground spin state and slow relaxation behavior.
