In this compound, europium exhibits the +3 oxidation state.

[3][4] Europium acetate can be obtained by stirring reaction of acetic acid and europium oxide under heating, and then diluting with water and crystallizing:[5] Europium can also directly participate in the reaction:[1] The anhydrous europium acetate crystallizes monoclinically in the space group C2/c (space group no.

[1] The sesquihydrate crystallizes monoclinically in the space group Cc (No.

[6] Europium acetate can be dissolved in water, acidified with acetic acid, and the compound of divalent europium [Eu(CH3COO)2(CH3COOH)(H2O)2] can be obtained by electrochemical reduction.

[1] Europium acetate can be decomposed by heating, and the hydrate first loses water to obtain anhydrous, and then passes through basic acetate EuOCH3COO, basic carbonate Eu2O2CO3, and finally obtains europium oxide.
