Yttrium iodide is a binary inorganic compound, a salt of yttrium and hydroiodic acid with the formula YI3.[2][3] The compound forms colorless crystals, soluble in water.
Synthesis
1. Heating yttrium and iodine in an inert atmosphere:
- [math]\ce{ 2Y + 3I2 -> 2YI3 }[/math]
2. Heating yttrium oxide with ammonium iodide:
- [math]\ce{ Y2O3 + 6NH4I -> 2YI3 + 6NH3 + 3H2O }[/math]
It can also be obtained by reacting yttrium oxide or yttrium hydroxide with hydroiodic acid.
Physical properties
Yttrium iodide forms colorless flaky crystals. The crystal structure is that of the BiI3 structure type.[4]
It dissolves well in water and ethanol. Does not dissolve in diethyl ether.
It also occurs as a tri- and hexahydrate.[5]
Applications
A precursor for YBCO superconducting materials in a lower temperature preparation.[6]
