Iron iodide (FeI₂) is a layered metal-halide compound that exists primarily as a research material rather than a commercial engineering grade. This material belongs to the family of transition metal halides and has attracted attention in materials science for its layered crystal structure, which exhibits weak van der Waals bonding between atomic planes. While not yet established in mainstream industrial applications, FeI₂ and related layered metal halides are being investigated for potential use in advanced electronics, energy storage, and two-dimensional material research, where the ability to exfoliate into thin layers could enable novel device architectures.
