We describe the HPLC separation and identification of N@C 60 and N 2 @C 60 . These species were observed after eleven sequential HPLC separations. Their retention times are in the same range as those of the other noninteractive endohedral species of C 60 , such as noble gas endohedral C 60 . The separation factors of these endohedrals were evaluated by using a mixture of hexane/toluene as eluent. We note that this is the first evidence for the N 2 @C 60 molecule existing in the form of endohedral C 60 complex.
