Typically, the metal will be one of the transition elements and the ligand will be oxygen or another chalcogenide or a cyanide group (though others are known). The chalcogenide metallates are known as oxometallates, thiometallates, selenometallates and tellurometallates; the cyanide metallates are known as cyanometallates.
Oxometallates include permanganate, chromate and vanadate.
Thiometallates include tetrathiomolybdate and similar ions.
Cyanometallates include ferricyanide and ferrocyanide.
Metallate is also used as a verb by bioinorganic chemistry to describe the act of adding metal atoms or ions to a site (synthetic ligand or protein.)
