Crystal Structure and Thermal Stability of Ag3(CHF2COO)3(H2O)2

X-ray diffraction analysis of [Ag₃(CHF₂COO)₃(H₂O)₂] revealed that its crystals are orthorhombic: space group Cmca, a = 13.809(4) Å, b = 15.975(2) Å, c = 12.244(2) Å, Z = 8. The thermogravimetric analysis showed that under the atmosphere of N₂ and at 101.3 kPa, silver difluoroacetate melts at 488 K; the thermal decomposition reaction occurs in the interval 493–548 K with the formation of Ag. Under the mass-spectral experiment conditions at 521 K, two processes occur simultaneously, namely, evaporation and decomposition. The following ions were detected in the mass-spectrum of silver difluoroacetate: Ag₂L⁺, Ag₂R⁺, Ag₂F⁺, Ag₂O⁺, Ag₂⁺, Ag⁺, LH⁺, RCO⁺, R⁺ (L = CHF₂COO, R = CHF₂).
