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 C 3-benzenes are a class of organic aromatic compounds which contain a benzene ring and three other carbon atoms. For the hydrocarbons with no further unsaturation, there are four isomers.
