Truly Monodisperse Molecular Nanoparticles of Cerium Dioxide of 2.4 nm dimensions : A {Ce100 O167} Cluster
Abstract Ultra‐small nanoparticles of CeO2 obtained in molecular form, so‐called molecular nanoparticles, have been limited to date to a family whose largest member is of nuclearity Ce40 with a {Ce40 O58} core atom count. Herein we report that a synthetic procedure has been developed to the cation [Ce100 O149(OH)18(O2 CPh)60(PhCO2 H)12(H2 O)20]16+, a member with a much higher Ce100 nuclearity and a {Ce100 O167} core that is more akin to the smallest ceria nanoparticles. Its crystal structure reveals it to possess a 2.4 nm size and high D2d symmetry, and it has also allowed identification of core surface features including facet composition, the presence and location of Ce3+ and H+(i.e. HO−) ions, and the binding modes of the ligand monolayer of benzoate, benzoic acid, and water ligands..
