Nanoscale polynuclear complexes are highly attractive because that they can be assembled into charming architectures and they have potential applications in many research fields, such as metalloenzyme models, catalysts, quantum computing, magnetic information storage, and magnetic cooling technology. [1] Such nanoscale clusters, constructed from the bottom up, have precedence over classical nanoparticles because elaborate control of their structures and properties is feasible. Metallamacrocycles (MMCs), a special class of polynuclear complexes with ringlike shapes, have also been designed to reach nanoscale size with the development of both molecular and crystal engineering. [2] However, most MMCs are assembled through bridging mononuclear metallic centers; the architecture of polymetallic-clusterbased-MMCs is still a great challenge. One strategy for construction of nanoscale cluster complexes is to adopt large macrocycle ligands with several coordination sites. [3] Recently, the multidentate macrocycle ligand p-tert-butylsulfonylcalix[4]arene (H4TBSOC) was successfully employed to give several lanthanide wheels, [4] and its analog p-tert-butylthiacalix[4]arene (H4TBSC) was used to build several MMCs that contained tetranuclear cobalt– calixarene cluster units. [5] Our interest is also directed toward nanoscale polynuclear complexes and the MMCs. [6]
