3D model of the rutile unit cell, similar to the structure of Iron(II) fluoride

Iron(II) fluoride, also known as ferrous fluoride, is an inorganic compound with the chemical formula FeF_. It is a pale green crystalline solid that is used in various industrial applications, including as a catalyst in organic synthesis and in the manufacture of ceramics.

Structure

Iron(II) fluoride crystallizes in the rutile structure, which is a common structure for many metal fluorides and oxides. In this structure, each iron ion is surrounded by six fluoride ions in an octahedral geometry. The fluoride ions are shared between adjacent iron centers, forming a three-dimensional network.

Properties

Iron(II) fluoride is a pale green solid that is relatively stable in air. It is insoluble in water but can dissolve in acids. The compound is known for its high melting point and thermal stability, making it suitable for high-temperature applications.

Applications

Iron(II) fluoride is used in the production of ceramics and as a catalyst in various chemical reactions. It is also employed in the synthesis of certain organic compounds, where it can facilitate fluorination reactions.

Safety

As with many metal fluorides, iron(II) fluoride should be handled with care. It can be harmful if ingested or inhaled, and appropriate safety measures should be taken to avoid exposure.
