✦ Synopsis

In a previous publication we conclude that: "Although planar aromatic hydrocarbons and graphite have provided appropriate points of analogy for the x-electron energy structure of CeO, it is clear that the magnetic response of CeO is unlike that of any other molecule yet encountered". In a recent Letter, Fowler, Lazzeretti and Zanasi (FLZ), report ab initio calculations on the magnetic susceptibility of lcosahedral Co,. FL2 conclude that CeO possesses '*... the strong diamagnetism expected of an aromatic system". The validity of this conclusion is addressed in the present note and it is shown that magnetic susceptibility of Cr,e is incompatible wnh its description as a normal aromatic molecule.
