Heterophase Synthesis of Silver Trifluoroacetate with Copper, Indium, and Zinc. Standard Enthalpy of Formation of Copper Trifluoroacetate
Russian Journal of Coordination Chemistry(2023)
Abstract
Solid-phase reactions of silver trifluoroacetate CF 3 COOAg with copper, indium, and zinc are studied by thermogravimetry, differential scanning calorimetry, and mass spectrometry. In a temperature range of 358–428 K, the reactions are found to afford trifluoroacetates of these metals without mass loss of the weighed samples. The obtained experimental data make it possible to calculate the enthalpy of formation of copper trifluoroacetate Δ_fH_298^^∘ (CF 3 СООСu, cr) = –1020.5 ± 18.0 kJ/mol.
