Chromium(III) Iodide

Chromium(III) Iodide Description

Chromium(III) iodide, also known as chromium triiodide, is an inorganic compound with the formula CrI3. It is a black solid that is used to prepare other chromium iodides.

Like the isomorphous chromium(III) chloride (CrCl3), chromium(III) iodide exhibits a cubic-closest packing arrangement in a double-layer crystal lattice. In this structure, chromium exhibits octahedral coordination geometry.

Chromium triiodide is stable in contact with oxygen and moisture, but at temperatures approaching 200 °C it reacts with oxygen and releases iodine. Like CrCl3, the triiodide exhibits slow solubility in water owing to the kinetic inertness of Cr(III). Addition of small amounts of chromous iodide accelerates the dissolving process.

CrI3 Crystal is a ferromagnetic semiconductor with Curie temperature (Tc) 61 K with significant magnetic anisotropy. Monolayer CrI3 has been confirmed to be an intrinsic 2D Ising ferromagnetic (FM) material with a suitable band gap of about 1.2 eV. SSC's CrI3 crystals are grown using chemical vapor transport techniques at our facilities.
