Previously, the activation of small molecules by cyclic alkyl(amino) carbene (cAAC)‐stabilized complexes of transition‐metal atoms in their zero oxidation state and two‐ coordination geometry has been visualized due to the fine tuning of the σ‐donation and π‐accepting property of cAAC. The authors report the activation of chalcogens using (cAAC) 2 Pt 0 complexes. The syntheses, isolation, and characterization of platinum complexes gave the air‐stable bis‐cAAC‐supported monomeric platinum(II) disulfide [(cAAC) 2 Pt(S 2 )] and the platinum sulfate [(cAAC) 2 PtSO 4 ]. The conversion of sulfate to reduced sulfur species in Nature by bacteria takes place in the oceans, where sulfate is the major oxidizing agent. This is a very important biological process. The bonding and electron‐density distributions of these complexes have been theoretically studied. More information can be found in the Communication by D. Koley, D. Stalke, H. W. Roesky et al. on page 12629.
