Iron (II ) fluoride is a chemical compound from the group of iron compounds and fluorides.

Production and representation

Iron (II ) fluoride can be obtained by reaction of iron (II ) chloride with hydrogen fluoride.

The product thus prepared is amorphous. To obtain it in crystalline form, it must be heated to 1000 ° C. Additionally you'll get pure white iron (II ) fluoride is only working when completely anhydrous. Otherwise, the connection turns gray - brown during the recrystallization.

Properties

Iron (II ) fluoride is a brown solid, which is slightly soluble in water. It has a crystal structure of rutile type.

Use

Iron (II ) fluoride as the starting material for the production of further iron ( II) compounds. Further, it is used in the organic chemistry as the catalyst for fluorination.
