Abstract A novel silver cluster ( SD/Ag48a ) co‐protected by p ‐MePhS − and CF 3 COO − ligands with an in‐situ generated unprecedented [Mo 8 O 28 ] 8− template has been synthesized under solvothermal condition. Single‐crystal X‐ray diffraction (SCXRD) and electrospray mass spectrometry (ESI‐MS) were used to determine the atom‐precise structure and solution behavior, respectively. Interestingly, the rare [Mo 8 O 28 ] 8− ion observed in the center of SD/Ag48a consists of 8 edge‐shared {MoO 6 } octahedra or can be deemed as three {Mo 4 O 4 } cubes fused together by sharing faces. The UV‐Vis spetcrum exhibits that a high‐energy (HE) wide absorption centered at ca. 365 nm, which can be assinged to intraligand (IL) π→π* transition absorption, whereas the low‐energy (LE) shoulder peak centered at ca. 500 nm can be ascribed to ligand‐to‐metal‐charge‐transfer (LMCT, S 3p→Ag 5 s) transition.
