Ferrous chloride · Iron(II) chloride
Ferrous chloride is a stable, semimetallic iron halide widely used as a precursor in chemical synthesis and industrial catalysis.
About Ferrous chloride
Ferrous chloride is a robust, thermodynamically stable inorganic compound that sits firmly on the convex hull of its chemical system. Its electronic character is defined as near-zero-gap, placing it in a semimetallic regime that distinguishes it from typical insulating metal halides.
This material is highly valued for its versatility in laboratory and industrial settings. Due to its structural stability and well-documented nature, it serves as a fundamental precursor in the synthesis of diverse iron-based complexes and as a reliable reagent in various chemical transformations.
Key Properties
Cross-validated computational properties for Ferrous chloride, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
