CAS Number: 7758-94-3
Synonyms: Iron(II) chloride, Iron dichloride, Ferrous dichloride, Iron monochloride, FeCl₂
Structural and Molecular Details
Ferrous chloride exists in both anhydrous and hydrated forms.
The most common hydrate is the tetrahydrate (FeCl₂·4H₂O), featuring octahedral coordination of iron by four water molecules and two chloride ions.
In the solid state, Fe²⁺ ions are coordinated in a distorted octahedral geometry.
