MnCl

Manganese chloride (MnCl) is an inorganic metal halide compound, though it should be noted that this stoichiometry is unusual—manganese chloride typically exists as MnCl₂ in practical applications. This material is primarily of research or specialized chemical interest rather than a structural engineering material. In industrial contexts, manganese chlorides are used as precursors for manganese oxide catalysts, in electroplating processes, and as reagents in chemical synthesis, but they are not commonly employed as bulk structural materials in mechanical or civil engineering.
