Self‐Assembly of A Novel Ag 48 Cluster Encapsulating an Unprecedented [Mo 8 O 28 ] 8− Anion Template
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...

A novel silver cluster (

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

consists of 8 edge‐shared {MoO

} 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. |
