Abstract
Calcium trifluoroacetate was prepared as its monohydrate Ca(CF3COO)(2). H2O by reaction of CaCO3 with an aqueous solution of CF3COOH. It has been esta blished by thermogravimetry and differential thermal analysis, that this sa lt possesses a low thermal stability. When heated in air, decomposition sta rts already at 106 degrees C, yielding the final product CaF2. Single cryst als of Ca(CF3COO)(2). H2O were obtained and found to be monoclinic (space g roup P2(1)/n); unit cell parameters: a = 9.465(2), b = 9.360(3), c = 16.565 (7) Angstrom.
