Cyclononatetraene is a organic compound with the formula C9H10. It is unstable and reorganized to cis-8,9-dihydroindene.[1]
Cyclononatetraenyl anion
Cyclononatetraenyl anion is stable. There are two cyclononatetraenyl anion:trans,cis,cis,cis-Cyclononatetraenyl Anion(Pac-Man shape) and cis,cis,cis,cis-cyclononatetraenyl anion(regular nonagon shape). cis,cis,cis,cis-cyclononatetraenyl anion is more stable than trans,cis,cis,cis-cyclononatetraenyl anion.[2]
Cyclononatetraenyl cation
Cyclononatetraenyl cation is also stable by Möbius aromaticity.[3][4]
