Abstract

Transition metal clusters are a unique class of chemical substances. Not only do they have well-defined molecular structures, they also exhibit interesting and potentially useful properties that are inherent to metal–metal bonded species. In this contribution, our efforts in developing synthetic methodologies necessary to bring a cluster system out of the limited sphere of fundamental cluster chemistry and into general synthetic applicability are summarized. Specifically, we have explored the uses of site-differentiated cluster complexes of the [Re63-Se)8]2+ core as stereospecific building blocks for supramolecular construction. A great variety of cluster-supported molecular and supramolecular architectures have been realized. These include Tinkertoy-like molecular cluster arrays featuring cluster units bridged by multitopic ligands and supramolecular assemblies of clusters engineered via hydrogen bonding and metal–ligand coordination. Some of these nanoscopic cluster-containing systems display rather interesting electronic and spectroscopic properties and, therefore, hold great potential in developing molecule-based electronic and optical materials. The work therefore marks the beginning of what promises to be an exciting new chapter in cluster chemistry.
