Аннотация:X-ray diffraction analysis of [Ag-3(CHF2COO)(3)(H2O)(2)] revealed that its crystals are orthorhombic: space group Cmca, a = 13.809(4) Angstrom, b = 15.975(2) Angstrom, c = 12.244(2) Angstrom, Z = 8. The thermogravimetric analysis showed that under the atmosphere of N-2 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+, (AgO+)-O-2.
