“…This distortion has been attributed to both the electron richness of the system and the ligand asymmetry, so it could be much less achievable in the highly symmetric metallocenes. Besides the slipped-sandwich structure, cisoid and transoid conformations have been presented by Hawthorne et al 106,107 and described by the same author 108,109 and by Nuńẽz et al 102 Intermediate gauche conformations may also be observed. 102 Undoubtedly, this is not just a matter of steric hindrance, since the cisoid conformation is preferred by d 6 Ni(IV) and Pd(IV) ions and the electronic distribution plays a key role 102 together with the intermolecular interactions and the anion environment.…”

Electrochemistry and Photoluminescence of Icosahedral Carboranes, Boranes, Metallacarboranes, and Their Derivatives

Icosahedral boranes, carboranes, and metallacarboranes are extraordinarily robust compounds with desirable properties such as thermal and redox stability, chemical inertness, low nucleophilicity, and high hydrophobicity, making them attractive for several applications such as medicine, nanomaterials, molecular electronics, energy, catalysis, environmental chemistry, and other areas. The hydrogen atoms in these clusters can be replaced by convenient groups that open the way to a chemical alternative to conventional "organic" or "organometallic" realms. Icosahedral boron cluster derivatives have been reviewed from different perspectives; however, there is a need for a review dedicated to the redox and photophysical characteristics of easily accessible borane and carborane derivatives, which are excellent materials for a wide range of applications. This review deals with the redox properties and photoluminescence behavior of this collection of compounds, as well as their influence on the properties of materials and devices whose working principles are related to electron-transfer or electron-promotion phenomena. We hope that this review will be of great value to boron cluster scientists and researchers working in the photoluminescence and electrochemistry fields who are interested in exploring the possibilities of these unique and promising systems.
