Trifluorides are compounds in which one atom or ion has three fluorine atoms or ions associated. Many metals form trifluorides, such as iron, the

rare-earth element The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), are a set o ...

s, and the metals in the groups 3, 13 and 15 of the periodic table. Most metal trifluorides are poorly soluble in water except ferric fluoride and indium(III) fluoride, but several are soluble in other solvents.
