Single-crystal X-ray structure of SD/Ag44. a The molecular structure of SD/Ag44. The inner POM anion template is shown in polyhedral mode (Color legend: Ag: purple; S: yellow; Mo: green; O: red; C: gray; N: blue). b The distributions of iPrS− ligands on the Ag44 shell sorted by different coordination modes individually colored. Black: μ3 and yellow: μ4. The polyhedral (c) and ball-and-stick (d) modes showing the inner Mo6O228− anion
