Dysprosium(III) iodide is a binary inorganic compound of dysprosium and iodine with the chemical formula DyI
3. [1]

Contents

Synthesis

Dysprosium(III) iodide can be obtained by reacting dysprosium with iodine.

2Dy + 3I → 2DyI3

Dysprosium(III) iodide can be obtained using the effect of mercury diiodide on dysprosium filings:

2Dy + 3HgI2 → 2DyI3 + 3Hg

Physical properties

Dysprosium(III) iodide is a hygroscopic yellow-green flaky solid [2] that is soluble in water. [3] The compound has a trigonal crystal structure of the bismuth(III) iodide type with the space group R3.

Uses

Antimony triiodide is the chemical compound with the formula SbI3. This ruby-red solid is the only characterized "binary" iodide of antimony, i.e. the sole compound isolated with the formula SbxIy. It contains antimony in its +3 oxidation state. Like many iodides of the heavier main group elements, its structure depends on the phase. Gaseous SbI3 is a molecular, pyramidal species as anticipated by VSEPR theory. In the solid state, however, the Sb center is surrounded by an octahedron of six iodide ligands, three of which are closer and three more distant. For the related compound BiI3, all six Bi—I distances are equal.
