Rational syntheses under controllable reducing conditions in the preparation of superatoms with cluster electron number not exceeding two are challenging. Herein a dithiolate-stabilized two-electron silver nanocluster, Ag 10 {S 2 P(O i Pr) 2 } 8 (1), is isolated via a self-redox reaction of Ag 7 (H){S 2 P(O i Pr) 2 } 6 without adding extra reducing agents. The metal framework of Ag 7 , a bicapped trigonal bipyramid, is highly correlated to that of Ag 10 , suggesting Ag 7 (H){S 2 P(O i Pr) 2 } 6 acts as both reducing agent and template in cluster growth. 1 is highly fluorescent at ambient temperature and TD-DFT calculations indicate that the emission is of 1P x →1S nature.
