In the paper, the temperature behavior of the vibrational spectrum of the [Formula: see text] crystal has been analyzed by Raman scattering. At a temperature of about 70 K the appearance of new lines was detected in the Raman spectra. The appearance of additional lines is associated with the fixation of the torsional vibration of the ethylenediamine chelate ring. Such a fixation testifies to the implementation of an order–disorder structural phase transition in these crystals. A model of the mechanism of the phase transition in the [Formula: see text] crystal involving the chelate ring of ethylenediamine is proposed.
