Hexamethylbenzene, also known as mellitene, is a hydrocarbon with the molecular formula C 12 H 18 and the condensed structural formula C 6 (CH 3) 6. It is an aromatic compound and a derivative of benzene , where benzene's six hydrogen atoms have each been replaced by a methyl group .

Another example is the elucidation of the electronic structure of the hexamethylbenzene dication. Three π bonding IBOs were found between the basal C 5 Me 5 plane and the apical C, reminiscent of Cp* coordination complexes. The three π bonds are thereby polarized towards the apical C, which in turn coordinates to a CH 3 + cation with its lone ...

The reaction occurs with the formation of 1,1-dimethoxyethane, CH 3 CH(OCH 3) 2, and hexamethylbenzene is produced by a side reaction. [ 5 ] [ 6 ] This rhodium(III) dimer can be reduced with zinc in the presence of CO to produce the rhodium(I) complex [Cp*Rh(CO) 2 ].
For example, following the publication of the structure of the dication of hexamethylbenzene, C 6 (CH 3) 2+ 6, in Angewandte Chemie International Edition, [6] Bachrach discussed its pyramidal geometry and six-coordinate carbon moiety in a blog post, demonstrating it is not hypervalent and explaining its three-dimensional aromaticity.

On the other hand, experimental research has confirmed that the pentagonal-pyramidal hexamethylbenzene ion, C 6 (CH 3) 6 2+, contains a hexacoordinate carbon atom. [8] Furthermore, a heptacoordinate carbon atom has been predicted to be involved in a stable hexagonal-pyramidal configuration of tropylium trication, (C 7 H 7) 3+. [9]
