The ions and salts form from them are also known as complex fluorides.

They can occur in salts, or in solution, but seldom as pure acids.

Fluoroanions often contain elements in higher oxidation states.

[1][2] Anions that contain both fluorine and oxygen can be called "oxofluoroanions" (or rarely "fluorooxoanions").

The following is a list of fluoroanions in atomic number order.
