title: Ti2C80 is more likely a titanium carbide endohedral metallofullerene (Ti2C2)@C78.
abstract: We show by means of density functional calculations that the previously synthesized metallofullerene Ti2C80 does not take the form of Ti2@C80, but is a titanium carbide endohedral metallofullerene, Ti2C2@C78, that has a C78(6-)(D3h) cage which follows faithfully the stable closed-shell electronic rule.
