CeZrCl6

CeZrCl6 is a chemical compound with the formula CeZrCl6. It is a mixed-valence halide compound containing both cerium and zirconium. In this compound, cerium is typically found in the +3 oxidation state, while zirconium is in the +4 oxidation state. The structure of CeZrCl6 is generally described as a layered perovskite-like structure, where the cerium and zirconium cations are coordinated by chloride anions.

This compound is often synthesized through solid-state reactions at elevated temperatures, typically involving mixtures of cerium(III) chloride, zirconium(IV) chloride, and sometimes additional chloride sources like alkali metal chlorides. The precise synthesis conditions can influence the resulting stoichiometry and crystal structure. CeZrCl6 has been investigated for its magnetic properties due to the presence of the paramagnetic cerium ion. It can exhibit interesting magnetic ordering at low temperatures. Research into CeZrCl6 also explores its potential applications in areas such as magnetic refrigeration or as a component in advanced materials, though it is not a widely commercialized substance. Its stability and reactivity are characteristic of many anhydrous metal chlorides.
