Cyanoacetylene

Cyanoacetylene is an organic compound with the formula C₃HN or H−C≡C−C≡N. It is the simplest cyanopolyyne. Cyanoacetylene has been detected by spectroscopic methods in interstellar clouds,^[2] in the coma of comet Hale–Bopp and in the atmosphere of Saturn's moon Titan,^[3] where it sometimes forms expansive fog-like clouds.^[4]
