Abstract We report two anion‐templated Ag 40 clusters, [Ag 40 (E) 4 (SO 4 ){S 2 P(OEt) 2 } 24 ](PF 6 ) 6 (E = S, 1 ; Se, 2 ). The anionic templates were generated in situ from the decomposition of dithiophosphate (dtp) ligands. The extrusion of sulfur undergoes disproportionation reactions to generate sulfide and sulfate anions, which provide the source of templates in the subsequent cluster assembly reactions. Two Ag 40 clusters display high similarity in their structures. The sulfide (selenide) anions and the central sulfate anion reveal a six‐coordinate and a rare dodecametallic dodecaconnective pattern, respectively. Four near‐equivalent [Ag 10 (E){S 2 P(OEt) 2 } 6 ] 2+ motifs were assembled via the connection of central sulfate anion to construct Ag 40 clusters. The cluster cation, [Ag 40 (E) 4 (SO 4 ){S 2 P(OEt) 2 } 24 ] 6+ , displayed in T symmetry, is unprecedented in anion‐templated silver clusters.
