A rare pearl of a neutral silicon atom in the formal oxidation state zero seems to evolve best in the oyster‐like coordination environment of a bidentate N‐heterocyclic carbene ligand. In their Communication on page 7147 ff. , M. Driess and co‐workers present the strikingly facile formation of this silicon pearl, which belongs to the novel class of theoretically predicted compounds termed silylones. (Graphics: Wernerwerke.)
