  "abstract": "Although the prediction of constructing three-dimensional self-assembled superclusters using icosahedral superatoms as building blocks dates back to 1987, this task remains a significant challenge, due to the difficulty in synthesizing and characterizing such clusters. In this study, the 8-electron superatom IrH2Ag19[S2P(OnPr)2]12 (1) was discovered for the first time, with IrH2 as the dopant. Its distinctive superatomic core, IrH2Ag12, was utilized as a building block for the self-assembly of a tetrahedral supercluster. A new hydride-containing 32-electron Ir/Ag alloy nanocluster, (IrH2)4Ag50[S2P(OnPr)2]22 (2), was prepared using homoleptic ligand. Similar to the prediction by Teo et al., the four icosahedra are assembled in a tetrahedral manner, which is reminiscent of tetrahedrane, to form the [(IrH2)4Ag42]14+ core passivated by [Ag8{S2P(OnPr)2}22]14–. Unlike previous studies that used M13 units, this study uniquely utilizes four (IrH2)@Ag12 units sharing six vertices to achieve the tetra-icosahedral kernel. The discovery of this 3D supercluster can more effectively help us understanding the growing process from nanoclusters to nanoparticles.",
