Manganese(II) iodide is the chemical compound composed of manganese and iodide with the formula MnI 2 (H2O) n. The tetrahydrate is a pink solid while the anhydrous derivative is beige. [2] Both forms feature octahedral Mn centers. Unlike MnCl 2 (H 2 O) 4 and MnBr 2 (H 2 O) 4 which are cis, MnI 2 (H 2 O) 4 is trans. [3]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Organomanganese chemistry is the chemistry of organometallic compounds containing a carbon to manganese chemical bond.In a 2009 review, Cahiez et al. argued that as manganese is cheap and benign (only iron performs better in these aspects), organomanganese compounds have potential as chemical reagents, although currently they are not widely used as such despite extensive research.

Manganese dioxide is the inorganic compound with the formula MnO 2. ... The carbonate is calcined in air to give a mixture of manganese(II) and manganese(IV) oxides.
The acid facilitates the conversion by the brown, Manganese-containing precipitate of the Iodide ion into elemental Iodine. The Mn(SO 4) 2 formed by the acid converts the iodide ions into iodine, itself being reduced back to manganese(II) ions in an acidic medium. Mn(SO 4) 2 + 2 I − (aq) → Mn 2+ (aq) + I 2 (aq) + 2 SO 2− 4 (aq)
