Octatetraynyl radical (C8H) is an organic free radical with eight carbon atoms linked in a linear chain with alternating single bonds and triple bonds (H−C≡C−C≡C−C≡C−C≡C•). In 2007 negatively charged octatetraynyl was detected in Galactic molecular source TMC-1, making it the second type of anion to be found in the interstellar medium (after hexatriynyl radical) and the largest such molecule detected to date.

Property Value
dbo:abstract
  • Le radical octatétraynyle est une espèce chimique de formule •C8H dans laquelle les huit atomes de carbone forment une chaîne où alternent liaisons simples et triples liaisons. L'anion octatétraynyle C8H− a été observé en 2007 dans le nuage moléculaire 1 du Taureau (TMC-1). (fr)
