Compound [Ag 42 S 5 (S t Bu) 25 (CF 3 COO) 4 (CO 3 )](CO 3 ) 0.5 ⋅CH 2 Cl 2 ⋅4CH 3 OH⋅9DMF ( 1 ) has been obtained and well defined. It consists of a multi‐shell structure involving two Ag centres, one Ag 5 S 5 pentagram, two Ag 5 S 5 pentagons and one Ag 25 S 15 shell. Compound 1 has been characterized by XPS, FT‐IR, PXRD, TGA, NMR, MS, UV/Vis spectrum, TEM and cyclic voltammetry. Temperature‐sensitive luminescent property of 1 has also been investigated.
