The future of subnitride chemistry appears promising: M6 octahedra with a central N atom have been detected in the new compound Na16Ba6N and in the compound hitherto described as “Ag8Ca3”; the latter is actually the isotypic Ag16Ca6N (with 0.7% N)! In these compounds the M6N octahedra are embedded in a matrix of Na and Ag, respectively. Numerous phases with the Ag8Ca3 structure such as Ni6Si2M3 and Ni6Al2M3 (M = rare‐earth metal) may likewise be stabilized by interstitial atoms.
