The hexatriynyl radical, C₆H, is an organic radical molecule consisting of a linear chain of six carbon atoms terminated by a hydrogen (H−C≡C−C≡C−C≡C•). The unpaired electron is located at the opposite end to the hydrogen atom, as indicated. Both experimental work and computer simulations on this species was done in the early 1990s.^[1]^[2]
