%X 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 and the surface Au atom. (HPd@Ag2Au8)3+ exhibited photoluminescence at
775 nm, with the enhanced quantum yield of 0.09%, although it is structurally
and electronically equivalent with (HPd@Au10)3+. This study demonstrates that hydride-mediated growth process is
a promising atomically-precise bottom-up synthetic method of new multimetallic
superatoms.
