We report on cross-linked carbon nitride nano-onions forming thin solid films by reactive unbalanced magnetron sputtering of graphite in an argon-nitrogen discharge. The onion shells, which contain up to 20 at% N, nucleate and grow atom-by-atom on substrates at temperatures as low as 200 °C. Nanoindentation studies reveals a highly resilient material that is relevant for wear-protective applications. Total energy calculations show the relative stability of C@sub 60-2n@N@sub 2n@ aza-fullerenes and suggests the existence of a novel C@sub 48@N@sub 12@ molecule with the unusual S@sub 6@ point group.
