Samarium(III) acetate is an acetate salt of samarium, with the chemical formula of Sm(CH₃COO)₃. It exists in the hydrate and tetrahydrate form. Its tetrahydrate can be obtained by dissolving samarium(III) oxide in 50% acetic acid solution, crystallizing and vacuum drying. The mixed anion acetate Cl₂·H₂O and Cl can be crystallized from SmCl₃·6H₂O and SmOCl in acetic acid solution respectively.
