A novel discrete neutral Cd 17 sulfide cluster (denoted CMM‐9) with seven corners has been synthesized by slow diffusion of methanol into a mixed solution (DMF/CS 2 = 1:1, weight ratio) containing an ionic starting material CMM‐4. The structures of CMM‐4 and CMM‐9 are determined from single crystal X‐ray diffraction data collected at 150 K. The structure of the new Cd 17 cluster is distinctly different from the well‐known C1 cluster that also has 17 Cd sites. The UV/Vis spectrum of the new cluster CMM‐9 revealed a maximum absorption at 305 nm in DMF solution, which is slightly red‐shifted compared to the regular C1 cluster (C1, [Cd 17 S 4 (SPh) 28 ] 2– , with a maximum absorption at 296 nm).
