General description

Manganese(II) acetylacetonate (Mn(acac)2) is a transition metal acetylacetonate that is trimeric in hydrocarbon solvents. It is monomeric and tetrahedral in its vapor state. It shows Mn-O bond energy of 65 kcal mol-1. It can be used with potassium permanganate in preparation of manganese triad (Mn(acac)3).
