· MnI2

Manganese iodide (MnI₂) is an inorganic halide compound belonging to the metal-halide family, characterized by divalent manganese cations coordinated with iodide anions. This material is primarily investigated in research contexts for applications in layered materials and electronic devices, rather than established industrial production. Its notable feature is the relatively weak interlayer bonding typical of layered halides, which makes it of interest for exfoliation studies and potential use in two-dimensional material research, particularly for optoelectronic and magnetic applications where manganese-based compounds offer unique electronic properties compared to transition metal alternatives.
