text: The reaction between praseodymium(III) nitrate and sodium fluoride will obtain praseodymium(III) fluoride as a green crystalline solid:
  : Pr(NO) + 3 NaF → 3 NaNO + PrF
  There are also literature reports on the reaction between chlorine trifluoride and various oxides of praseodymium (PrO, PrO and PrO), where praseodymium(III) fluoride is the only product. The reaction between bromine trifluoride and praseodymium oxide left in the air for a period of time also produces praseodymium(III) fluoride, but the reaction is incomplete; the reaction between praseodymium(III) oxalate hydrate and bromine trifluoride can obtain praseodymium(III) fluoride, and carbon is also produced from this reaction. Praseodymium(III) fluoride can also be obtained by reacting praseodymium oxide and sulfur hexafluoride at 584 °C.
