Two heterometallic [(Dy6Mn12III)-Mn-III] clusters comprising of the same [(Mn8O13)-O-III] fragment, four isolated Mn-III ions and two linear [Dy-3(III)] 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 [Dy-3(III)] 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.
