Description

Description générale

Manganese(II) acetate tetrahydrate is a hydrated salt of manganese. Kinetic studies suggest that its dehydration takes place in two-step reaction involving the loss of two water molecules. Its crystal structure has been investigated by X-ray studies. Its crystals exhibit monoclinic crystal system and space group P2₁/c.

Application

Manganese(II) acetate tetrahydrate may be used in the sol gel synthesis of doped TiO₂ containing different amounts of Mn²⁺.
