A gallide is an inorganic chemical compound containing anions composed of gallium atoms.

Gallium is outside the Zintl border, and so does not always form Zintl compounds with balanced electron numbers. However for alkali metals compounds contain electron-precise icosahedral Ga12 or octahedral Ga6 clusters.

Some gallides form endohedral clusters, where a cluster of gallium atoms surrounds another metal atom.

Formation
Gallides are formed by heating a metal with gallium, and then cooling slowly till crystallisation takes place. Liquid gallium is them remove by centrifuge.
