General description

Manganese (II) chloride is a pink crystalline solid that is highly soluble in water. The anhydrous form of Manganese(II) chloride assumes a structure similar to layered cadmium chloride. It is a key starting material for the synthesis of organomanganese compounds.

Application

Manganese(II) chloride can be used:
  • As a precursor to synthesize manganese oxide nanoparticles.
  • To fabricate Mn(ll) coordinated polyaniline electrodes for supercapacitors.
  • To prepare thermally activated high anodic capability MOFs for Li-ion batteries.
  • As a starting material to synthesize polymer composite films withenhanced optical properties.
