Properties.
Praseodymium(III) iodide forms green crystals, which are soluble in water. It forms orthorhombic crystals which are hygroscopic. It crystallizes in the PuBr3 type with space group "Cmcm" (No. 63) with "a" = 4.3281(6) Å, "b" = 14.003(6) Å and "c" = 9.988(3) Å. It decomposes through an intermediate phase 2 PrI3·PrOI to a mixture of praseodymium oxyiodide and praseodymium oxide (5 PrOI·Pr2O3).
Pr2O3 + 6 HI + 15H2O → 2 PrI3·9H2O
2 PrI3 + Pr → 3 PrI2
