Gadolinium acetate is the acetate salt of the lanthanide element gadolinium with the chemical formula Gd(CH3COO)3.

It is a colorless crystal that is soluble in water and can form a hydrate.

[1] Its tetrahydrate has ground state ferromagnetism.

[2] The tetrahydrate of gadolinium acetate can be crystallized from aqueous solution by reaction of gadolinium oxide and acetic acid:[2] The complex [Gd4(CH3COO)4(acac)8(H2O)4] can be obtained by the reflux reaction of gadolinium acetate and acetylacetone in the presence of triethylamine in methanol solution.
