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 It is an aromatic compound and a derivative of benzene , where benzene's six hydrogen atoms have each been replaced by a methyl group .

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]
The complex can be viewed as an edge-shared bioctahedral structure. (Benzene)ruthenium dichloride dimer reacts with Lewis bases to give monometallic adducts: [(C 6 H 6)RuCl 2] 2 + 2 PPh 3 → 2 (C 6 H 6)RuCl 2 (PPh 3)
Benzene and cyclohexane have a similar structure, only the ring of delocalized electrons and the loss of one hydrogen per carbon distinguishes it from cyclohexane. The molecule is planar. [ 58 ] The molecular orbital description involves the formation of three delocalized π orbitals spanning all six carbon atoms, while the valence bond ...
Side view of ABA layer stacking in graphite. Graphite consists of stacked sheets of covalently bonded carbon. [5] [6] The individual layers are called graphene.In each layer, each carbon atom is bonded to three other atoms forming a continuous layer of sp 2 bonded carbon hexagons, like a honeycomb lattice with a bond length of 0.142 nm, and the distance between planes is 0.335 nm.
