Ligand oximation “converts” an hexametallic MnIII wheel into a dodecametallic MnIII wheel, while the magnetic exchange switches from ferro- to antiferromagnetic.
The use of the novel pro-ligand H4L combining the complimentary phenolic oxime and diethanolamine moieties in one organic framework, results in the formation of the first example of a [MnIII12] truncated tetrahedron.
