Cubane {CuII4} Cluster as a Precursor for the Preparation of a Mixed‐Valent {CuII12CuI2} Core

Current interests in the chemistry of high-nuclearity transition- metal complexes draw from their utility in the emerging science of nanomaterials,[1] as models for the multimetal active sites of metal-storage proteins,[2] and as single molecule magnets (SMMs).[3,4] In addition, such super-sized molecules often show a variety of supramolecular interactions.[5] The self-assembly process of generating a high-nuclearity cluster from a mono- or dimeric precursor generally involves low-dentate organic ligands.
