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
