Chemical compound

Yttrium iodide is a binary inorganic compound, a salt of yttrium and hydroiodic acid with the formula YI
3. The compound forms colorless crystals, soluble in water.

Synthesis

1. Heating yttrium and iodine in an inert atmosphere:

2 Y + 3 I 2 2 YI 3 {\displaystyle {\ce {2Y + 3I2 -> 2YI3}}}

2. Heating yttrium oxide with ammonium iodide:

Y 2 O 3 + 6 NH 4 I 2 YI 3 + 6 NH 3 + 3 H 2 O {\displaystyle {\ce {Y2O3 + 6NH4I -> 2YI3 + 6NH3 + 3H2O}}}

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 BiI
3 structure type.

It dissolves well in water and ethanol. Does not dissolve in diethyl ether.

It also occurs as a tri- and hexahydrate.

Applications

A precursor for YBCO superconducting materials in a lower temperature preparation.
