Praseodymium(III) sulfide is an inorganic chemical compound with chemical formula Pr2S3.
Preparation
[edit]Praseodymium(III) sulfide can be obtained by reacting praseodymium(III) oxide and hydrogen sulfide at 1320 °C:[1]
- Pr2O3 + 3H2S → Pr2S3 + 3H2O
It could also be obtained by directly reacting sulfur with metallic praseodymium:[2]
- 2Pr + 3S → Pr2S3
