organic chemistry - 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


structure formula


or


structure formula 2


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





*) Some structures in the Wikipedia article have the two positive charges placed into the cyclopentadienyl (aromatic) ring, which I think is incorrect.
