Mellitic trianhydride, C12O9: the aromatic oxide of carbon.
Use of the ipsocentric method to map the pattern of current induced by a perpendicular magnetic field in the mellitic trianhydride molecule shows that, in addition to localized current associated with the carbonyl and oxygen centers, the field induces a strong central benzene-like ring current, thus indicating aromaticity on the magnetic criterion for this polycyclic oxide of carbon.
