Abstract

Calcium trifluoroacetate was prepared as its monohydrate Ca(CF3COO)2ċH2O by reaction of CaCO3 with an aqueous solution of CF3COOH. It has been established by thermogravimetry and differential thermal analysis that this salt possesses a low thermal stability. When heated in air, decomposition starts already at 106°C, yielding the final product CaF2. Single crystals of Ca(CF3COO)2ċH2O were obtained and found to be monoclinic (space group P21/n); unit cell parameters: a=9.465(2), b=9.360(3), c=16.565(7) A.
