PbCl4
lead tetrachloride · lead(IV) chloride
Lead tetrachloride is a metastable, semiconducting inorganic liquid used primarily as a specialized reagent in chemical synthesis.
About lead tetrachloride
Lead tetrachloride is a volatile, metastable inorganic compound that exists as a yellow oily liquid. It is characterized by its semiconducting electronic nature and serves as a reactive source of lead in its higher oxidation state. Due to its inherent instability, it requires careful handling and storage conditions to prevent decomposition into lead dichloride and chlorine gas.
This compound is primarily utilized in specialized chemical synthesis and research environments where a potent chlorinating agent or a source of reactive lead is required. Its structural complexity is evidenced by its appearance across multiple crystallographic databases, reflecting its significance in fundamental inorganic chemistry studies.
Key Properties
Cross-validated computational properties for lead tetrachloride, 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.
