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.
