High‐Nuclearity, High‐Symmetry, High‐Spin Molecules: A Mixed‐Valence Mn₁₀ Cage Possessing Rare T symmetry and an S=22 Ground State

Taking the high road: The unification of azide and hmp− (hmpH=2-(hydroxymethyl)pyridine) ligands has provided a route to two salts of a new Mn10 cation with an aesthetically pleasing, high-symmetry structure. The cation (see excerpt of structure; MnII yellow, MnIII blue, O red, N green, C gray) is completely ferromagnetically coupled and possesses an S=22 ground state, one of the highest values ever reported.
