✦ Synopsis

Electric permittivity e*= e'-ie" of nickel-hexammino nitrate (NHN) has been measured within the range of temperature from 9 to 300 K at a frequency of 8.8 GHz (X-band). It has been found that the phase transitions at Tkl =247K and Tk2 =90K are discontinuous structural transitions between centrosymmetric phases, whereas the transition at T c = 63 K is a continuous phase transition (glass?).
