It is possible that "BaCl2n" is a typo and was intended to be BaCl2, or it might refer to a more complex, possibly hypothetical or context-specific structure not represented by standard nomenclature. Barium chloride (BaCl2) is an ionic compound composed of barium cations (Ba2+) and chloride anions (Cl-). It is a white crystalline solid that is soluble in water. Barium chloride has various applications, including in the production of other barium compounds, as a flux in metallurgy, and in pyrotechnics to produce a green color. It is also used in some medical imaging procedures as a radiocontrast agent, although its use has declined due to toxicity concerns. The toxicity of barium compounds is a significant factor in their handling and application.
