We present candidate structures for the most stable isomers for the VSc2N@C70, VSc2N@C76, VSc2N@C78, and VSc2N@C80 using a systematic procedure that involves all possible isomers of the host fullerene cages. Subsequently, a detailed investigation of structural and electronic properties of the lowest energy isomers is performed using density functional theory in combination with large polarized Gaussian basis sets. The search correctly identifies the experimentally observed VSc2N@C80 isomer as the most stable structure. The structural analysis shows that onlyVSc2N@C70 has a non-IPR cage among the four endohedral fullerenes. Respectively, VSc2N@C70 and VSc2N@C76 have nearly degenerate spin states with total spin S=0 and S=1. All the lowest energy cages are energetically stable and show significant electron accepting capacity comparable to C60.
