Nickel(II) acetylacetonate dihydrate

Nickel chloride hexahydrate was dissolved in water and added to a methanol solution of acetylacetone under stirring. Then sodium acetate trihydrate solution was added, stirred, dissolved, heated, concentrated, cooled, and a blue-green precipitate was formed. The precipitate was filtered, washed with cold water, and dried to obtain crude Nickel(II) acetylacetonate dihydrate. The crude [1] was recrystallized in methanol to obtain the refined [1].

light green to green powder

Nickel(II) acetylacetonate dihydrate acts as a curing agent for epoxy resins and a catalyst for organic reactions.
