Thermal decomposition of N₂H₆[CrF₅(H₂O)] has been investigated by thermoanalytical, X-ray and IR spectroscopic methods. Under quasi-isobaric conditions the decomposition takes place in several steps. The intermediate N₂H₆CrF₅ has been found which crystallizes monoclinically with α = 555.0 pm, b = 1084.6 pm, c = 777.0 pm, β = 91.76°. N₂H₆CrF₅ decomposes via an amorphous intermediate to give pure rhomboedrical CrF₃ as the final product. One of the intermediate has been identified as chromium fluoride ammoniate CrF₃ 0.4 NH₃. No hydrolysis reactions have been observed.
