Synthesis of Trimetallic (HPd@M₂Au₈)³⁺ Superatoms (M = Ag, Cu) via Hydride-Mediated Regioselective Doping to (Pd@Au₈)².

ABSTRACT: We have recently reported that hydride (H^-) doped superatom (HPd@Au₈)⁺ protected by eight PPh₃ ligands selectively grew into (HPd@Au₁₀)³⁺ by the nucleophilic addition of two Au(I)Cl units. In the present study, (HPd@Au₈)⁺ was successfully converted to unprecedented trimetallic (HPd@M₂Au₈)³⁺ superatoms (M = Ag, Cu) by controlled doping of two Ag(I)Cl or Cu(I)Cl units, respectively. Single-crystal X-ray diffraction analysis demonstrated that two Ag(I) or Cu(I) ions were regioselectively incorporated. Theoretical calculations suggested that hydrogens in (HPd@M₂Au₈)³⁺ (M = Au, Ag, Cu) occupy the same bridging site between the central Pd atom
