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 {S P(O Pr) } (1), is isolated via a self-redox reaction of Ag (H){S P(O Pr) } without adding extra reducing agents. The metal framework of Ag , a bicapped trigonal bipyramid, is highly correlated to that of Ag , suggesting Ag (H){S P(O Pr) } 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 →1S nature.
