Cadmium acetate is the chemical compound with the formula Cd(O
2CCH

2(H
2O)
2. The compound is marketed both as the anhydrous form and as a dihydrate, both of which are white or colorless. Only the dihydrate has been verified by X-ray crystallography.

## Preparation, reactions, and uses

It forms by treating cadmium oxide with acetic acid:[3][4]

CdO + 2 CH
3CO
2H + H
2O → Cd(O
2CCH

2(H
2O)

It can also be prepared by treating cadmium nitrate with acetic anhydride.[5]

Cadmium acetate has few applications. By reaction with trioctylphosphine selenide, it has often been used as a precursor to cadmium selenide and related semiconductors.[6]

## Structure of the dihydrate

Fragment of the structure of cadmium diacetate dihydrate. Legend: red = O, black = C, blue = Cd.

Unlike the coordination geometry of zinc in zinc diacetate dihydrate, cadmium is seven coordinate in Cd(O
2CCH

2(H
2O)
2.[7] It is a coordination polymer, featuring acetate ligands interconnecting cadmium centers.

## Safety

Cadmium compounds are considered Group 1 carcinogens by the IARC.
