Removing Compositional Boundaries in Mixed-Linker Keplerate Clusters

The formation of a self-assembled multi-heterometal Keplerate polyoxomolybdate demonstrates compositional control of linker groups in spherical clusters. The resulting partially reduced {Mo(72)(V/VI)Fe(20)(III)V(8)(IV)Mo(2)(V)}-type cluster exhibits intramolecular ferrimagnetic ordering characteristic of such mixed-spin Keplerate systems.
