The first set of systems having C‐Ng‐N bonding unit is predicted herein through the analysis of stability and bonding in NCNgNSi (Ng = Kr‐Rn) family. They are thermochemically stable with respect to all dissociation channels, but for the one producing CNSiN and free Ng. Ng is bound with the adjacent atoms through a delocalized 3c–3e σ‐bond involving a C‐Ng‐N moiety and a totally delocalized 5c‐2e σ‐bond in these compounds, which represents an unprecedented bonding nature, as in Ng‐inserted compounds Ng usually forms one covalent and one ionic bond with the neighboring elements.
