Abstract

Anisotropy can be introduced into the [Mn₁₉]-aggregate, which currently has the highest known spin ground state of S = 83/2, by the targeted replacement of the central Mn^II cation with Dy^III leading to a [Mn₁₈Dy] complex with the same core topology showing slow relaxation of the magnetisation.
