1842 J. W. Draper Kane's Elements Chem. (Amer. ed.) xxi. 567 There does not appear to be any acetylide of hydrogen corresponding to ammonia.
2. Any of a group of saltlike compounds formed from acetylene by the replacement of one or both of the hydrogen atoms by a metal; (also) either of the anions C ≡ C2− and HC ≡ C−, present in such compounds.An example of an acetylide is calcium carbide, CaC2. Some acetylides such as those of silver and copper are spontaneously explosive.
