title: Comment on the phase transition mechanism in diglycine methanesulfonate.
abstract: The transition mechanism revised: The transition in diglycine methanesulfonate at 133 K has an order-disorder character. It has been evidenced that the previously postulated by Zhou and coworkers (Chem. Asian J.- 2014, 9, 996-1000) displacive mechanism of this transition is a simple consequence of the improper analysis of the X-ray diffraction and calorimetric experimental data.
