Manganese (II) iodide is a chemical compound of manganese from the group of iodides .

Extraction and presentation

Manganese (II) iodide can be obtained by reacting manganese (II) oxide with hydrogen iodide .

The tetrahydrate can be prepared by reacting manganese (II) carbonate with hydriodic acid. The anhydrous form can be produced from it by dehydration in a vacuum .

properties

Manganese (II) iodide is a pink solid that turns brown in air under the influence of light as a result of the oxidation of the iodide ion to iodine. It has a trigonal crystal structure of the cadmium (II) iodide type ( polytype 2H ) with the space group P 3 m 1 (space group no.164) . It dissolves in water and decomposes. The tetrahydrate has a monoclinic crystal structure with the space group P 2 ₁ / c (No. 14) . Template: room group / 164Template: room group / 14
