Via the TDPAC technique and complementary x-ray diffraction analysis, the thermal decomposition of (NH4)2ZrF6 has been observed to occur in the range 400-800 K according to the thermolysis scheme .Assuming that the first transformation takes place through the simple chemical reaction (NH4)2ZrF6 -> NH4ZrF5 + NH4F the corresponding activation energy has been determined to be E_a = (82 +/- 6) kJ/mol. The hyperfine parameters of the NH4Zr2F9 decomposition product have been determined between 14 and 560 K.A complete analogy with the isomorphous compound NH4Hf2F9 was observed.
