Influencing the Orientation of Jahn-Teller Axes in Butterfly-Like MnIII4 Clusters.

A bis-phenolate that has structural similarities to both calix[4]arene and the oxacalix[ n]arenes provides access to a 'butterfly'-like Mn₄ cluster in which all metals are in the oxidation state+3. Specific properties of this ligand, in comparison to others in the literature, offer a route to influencing the orientation of the Jahn-Teller axes within this cluster motif, which possesses a rare oxidation state arrangement.
