· MnBr2

Manganese dibromide (MnBr2) is an inorganic halide compound consisting of manganese and bromine, belonging to the family of transition metal halides. While not a structural metal in the conventional sense, MnBr2 is primarily of interest in materials research and specialized chemical applications, including layered crystal systems relevant to two-dimensional materials research. The compound has potential applications in catalysis, battery chemistries, and advanced materials where manganese's variable oxidation states and bromine's reactivity can be leveraged.
