General description

Manganese(III) acetate dihydrate is a coordination compound of manganese in the +3 oxidation state, exhibiting moderate solubility in water and acetic acid. It is used as a precursor for synthesizing manganese oxides and other manganese-containing materials. These materials have applications in batteries, catalysis, and other energy-related technologies. Additionally, it is also used as a mild and selective oxidizing agent in organic synthesis.

Application

Manganese(III) acetate dihydrate can be used as:      
  • A precursor in the synthesis of manganese oxide (Mn3O4) nanostructures, which are employed as anode materials in lithium-ion batteries.
  • A manganese source in the sol-gel synthesis of Mn-doped ZnO thin films. The incorporation of manganese ions into the ZnO lattice is essential for modifying the electronic and optical properties of the films.
  • A precursor for the synthesis of manganese oxide nanoparticles using a sol-gel process. These nanoparticles are evaluated for their performance in supercapacitor applications.     
  • A mild and selective oxidizing agent. Catalyzes allylic oxidation of a variety of alkenes in the presence of tert-butylhydroperoxide. Reagent used for radical cyclizations and α-keto-acetoxylation.

Physical form

Crystallographic evidence suggests this material is an oxo-centered triangle of Mn(III) with bridging acetates having the molecular formula: Mn3O(OAc)9 · 6H2O.
