Clusters of magnets : The first examples of manganese single‐molecule magnets (SMMs) consisting exclusively of trivalent metal centers are reported. These are hexanuclear clusters containing the [Mn III 6 (μ 3 ‐O) 2 (μ 2 ‐OR) 2 ] 12+ core (see picture, Mn yellow, O red) and have an S =4 ground state. Variation of the oxygen‐containing ligands allows a potentially large family of SMMs to be prepared.
