Dimanganese decacarbonyl is a chemical compound of manganese from the group of carbonyl complexes .

Extraction and presentation

Dimangandecacarbonyl can be obtained by pressure carbonylation of manganese (II) salts, such as. B. Manganese (II) chloride or manganese (II) acetate can be obtained.

${\displaystyle \mathrm {2\ Mn(CH_{3}CO_{2})_{2}+10\ CO\ {\xrightarrow[{300\ bar\ CO}]{Al(C_{2}H_{5})_{3}}}Mn_{2}(CO)_{10}} }$

properties

Dimanganese decacarbonyl is a golden yellow, light-sensitive solid that is insoluble in water. It is soluble in practically all organic solvents and is stable in air for a long time. It sublimes rapidly in a high vacuum even at room temperature. Its solutions are sensitive to air.

use

Dimanganese decacarbonyl is a raw material for manganese carbonyl compounds and is used as a catalyst and anti-knock agent.
