Praseodymium(III) fluoride is an inorganic compound with the formula PrF₃, being the most stable fluoride of praseodymium.

Production

The reaction between praseodymium(III) nitrate and sodium fluoride will produce praseodymium(III) fluoride as a green crystalline solid:^[3]

Pr(NO₃)₃ + 3 NaF → 3 NaNO₃ + PrF₃
