"Two-Dimensional van der Waals Nanoplatelets with Robust Ferromagnetism". Zhu, Guomin Lin, Zhong De Yoreo, James J. Regan, Annie Malinowski, Paul Jiang, Qianni Kluherz, Kyle T. "Structural Properties of Chromium(III) Iodide and Some Chromium(III) Mixed Halides". Handbook of Inorganic Compounds, Second Edition. Ĭhromium triiodide was one of the first materials which was discovered to be a magnetic two-dimensional material that has great potentials for spintronics devices. Ĭhromium triiodide can also be prepared as nanoplatelets from the alkoxide Cr(OC(CH 3)(C(CH 3) 3) 2) 3. 100 (1 rating) ANSWER:305.80504amu FORMULA WEIGHT OF Chromium (II) iodide (CrI2) Cation Cr2+ Atomic weight 51.9961 number of ions. Addition of small amounts of chromous iodide accelerates the dissolving process. Chromium has four oxidation states: 2, 3, 4, and 6.Iodine has one, and its -1.There will be a iodide for each oxidation state of chromium.CrI2 Chromium (II) iodideCrI3 Chromium (III) iodideCrI4. Like CrCl 3, the triiodide exhibits slow solubility in water owing to the kinetic inertness of Cr(III). Cu 2 O Copper (I) Oxide CrCl 2 Chromium (II) Chloride CuO Copper (II) Oxide CrS Chromium (II) Sulphide CuS Copper (II) Sulphide CrI 3 Chromium (III) Iodide. Ĭhromium triiodide is stable in contact with oxygen and moisture, but at temperatures approaching 200 ☌ it reacts with oxygen and releases iodine. To obtain high purity samples, the product is thermally decomposed at 700 ☌ to sublime out chromium(II) iodide. Download this stock image: CrI2 chromium(II) iodide CAS 1 chemical substance in white plastic laboratory packaging - 2M47TAM from Alamys library. Preparation and properties Ĭhromium triiodide is prepared by the direct reaction of chromium metal with an excess of iodine. ![]() In this structure, chromium exhibits octahedral coordination geometry. Like the isomorphous chromium(III) chloride ( CrCl 3), chromium(III) iodide exhibits a cubic-closest packing arrangement in a double-layer crystal lattice. It is a black solid that is used to prepare other chromium iodides. Chromium(III) iodide, also known as chromium triiodide, is an inorganic compound with the formula Cr I 3.
