 Custom Search Lewis Dot of the Dicarbide Ion (Acetylide Ion) C22- From- http://en.wikipedia.org/wiki/Acetylide -Some salts of the C22− anion are traditionally called carbides, e.g. calcium carbide Ca2+·C22− and lithium carbide (Li+)2·C22−. Some acetylides are explosive, and their accidental formation is a major safety risk in acetylene processing or storage. Acetylides are very useful reagents in organic chemistry.
