Erbium(III) acetate is the acetate salt of erbium, with the proposed chemical formula of Er(CH₃COO)₃. It can be used to synthesize some optical materials.^[2]

Physical properties

The tetrahydrate of erbium(III) acetate is thermally decomposed at 90 °C, giving a proposed anhydride:

Er(CH₃COO)₃·4H₂O → Er(CH₃COO)₃ 4 H₂O

Continued heating to 310 °C will form ketene:

Er(CH₃COO)₃ → Er(OH)(CH₃COO)₂ CH₂=C=O

At 350 °C, the proposed Er(OH)(CH₃COO)₂ loses acetic acid to yield a material of the formula ErOCH₃COO, forming Er₂O₂CO₃ at 390 °C, finally obtaining Er₂O₃ at 590 °C.^[3]
