Electron count and electronic structure of bare icosahedral Au32 and Au33 ionic nanoclusters and ligated derivatives. Stable models with intermediate superatomic shell fillings (2020)
Wang, Qi; Halet, Jean François; Kahlal, Samia; Muñoz-Castro, Álvaro; Saillard, Jean Yves (NLM (Medline), 2020-09-23)DFT calculations were carried out on bare Au32 and Au33 nanoclusters with various charges, in order to analyze their stability with respect to different cluster electron numbers. Results indicate that in addition to the ... -

On Heteronuclear Isoelectronic Alternatives to [Au13(dppe)5Cl2]3+: Electronic and Optical Properties of the 18-Electron Os@[Au12(dppe)5Cl2] Cluster from Relativistic Density Functional Theory Computations (2021)
Wei, Jianyu; Rodríguez-Kessler, P. L.; Halet, Jean François; Kahlal, Samia; Saillard, Jean Yves; Muñoz-Castro, Alvaro (American Chemical Society, 2021)The development of well-defined atomically precise heteronuclear nanoclusters passivated by protecting ligands is presently a booming area, owing to the fact that doping well-known homonuclear nanostructures allows fine-tuning ... -
