Thallium(III) acetate

Thallium(III) acetate is one of two acetate salts of thallium, with the chemical formula Tl(CH₃COO)₃. Thallium acetate is a toxic depilatory^[1] and rat poison. Thallium acetate was widely marketed as Koremlu during the 1930s. Women who suffered the side effects of the popular product sued the company, forcing it to bankruptcy in 1932.^[2] A dose of 8 mg/kg will cause acute poisoning, and the minimum lethal dose for adults is 12 mg/kg.^[3]

Preparation

Thallium acetate can be obtained by reacting 80% acetic acid with thallium(III) oxide, and the product crystallizes in acetic anhydride.^[4]

Properties

Anhydrous thallium(III) acetate crystallises in the monoclinic system with space group C2/c. The unit cell dimensions are a = 15.54 Å b = 8.630 Å and c = 7.848 Å with β = 113.92°. There are four formula per unit cell. and density is 2.57. Three acetate ions are chellated to each thallium ion.^[5]
