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]

Preparation

The tetrahydrate of gadolinium acetate can be crystallized from aqueous solution by reaction of gadolinium oxide and acetic acid:^[2]

Gd₂O₃ + 6 HOAc + 5 H₂O → [(Gd(OAc)₃(H₂O)₂)₂]·4H₂O

Properties

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.^[3]
