IUPAC name of C₆(CH₃)₆²⁺ What is the correct IUPAC name (or least incorrect one, if the current rules can't precisely describe that) of the interesting species $\ce{[C6(CH3)6]^{2+}}$ (which is extensively discussed here), containing exotic hexacoordinate pyramidal carbocation* ?  

The structure can be drawn as



or



My guess is methyl(pentamethyl-η5-cyclopentadienyl)carbon(2+).



&#x2a;) Some structures in the Wikipedia article have the two positive charges placed into the cyclopentadienyl (aromatic) ring, which I think is incorrect.
From the IUPAC Gold Book:


  Carbocations may be named by adding the word 'cation' to the name of the corresponding radical. Such names do not imply structure (e.g. whether three-coordinated or five-coordinated carbon atoms are present).


So since this is the dication of hexamethylbenzene, it would probably  least incorrectly be called hexamethylbenzene dication. At the very least, this seems to be how a lot of people refer to it (or more verbosely, pentagonal-pyramidal hexamethylbenzene dication).
