Carbide - Wikipedia

Several carbides are assumed to be salts of the acetylide anion C 2 2– (also called percarbide), which has a triple bond between the two carbon atoms. Alkali metals, alkaline earth metals, and lanthanoid metals form acetylides, e.g., sodium carbide Na 2 C 2, calcium carbide CaC 2, and LaC 2. Lanthanides also form carbides (sesquicarbides, see below) with formula M 2 C 3.
