An N‐heterocyclic silylene functionality at a Si 6 siliconoid is shown capturing sulfur with a landing net in the cover art. This directing effect—active also for selenium and tellurium—results in the expansion of the cluster instead of oxidation of the unsaturated silicon vertices shown with padlocks. The process is suggested as a model reaction for the diffusion of chalcogens from silicon surfaces into the bulk. More information can be found in the Communication by D. Scheschkewitz et al. on page 16599.
