![]() ![]() Uses Ĭhromium(III) fluoride finds some applications as a mordant in textiles and as a corrosion inhibitor. ![]() The anhydrous form is produced from hydrogen fluoride and chromic chloride: CrCl 3 + 3 HF → CrF 3 + 3 HClĪnother method of synthesis of CrF 3 involves thermal decomposition of 3 (ammonium hexafluorochromate(III)):Ī mixed valence compound Cr 2F 5 (chromium(II,III) fluoride) is also known. Production Ĭhromium(III) fluoride is produced from the reaction of chromium(III) oxide and hydrofluoric acid: Cr 2O 3 + 6 HF + 9 H 2O → 2 F 3 In the hydrates, some or all of the fluoride ligands are replaced by water. In the anhydrous form, the six coordination sites are occupied by fluoride ligands that bridge to adjacent Cr centres. Like almost all compounds of chromium(III), these compounds feature octahedral Cr centres. The anhydrous form sublimes at 1100–1200 ☌. The compound CrF 3 is a green crystalline solid that is insoluble in common solvents, but the hydrates F 3 (violet) and F 3♳H 2O (green) are soluble in water. Chromium(III) fluoride is an inorganic compound with the chemical formula Cr F 3. ![]()
