Abstract:
We report the study of a reversible phase transition accompanied by pressure-induced disordering in bis(dl-serinium) oxalate dihydrate which was observed at hydrostatic pressures of ∼4 GPa. The disordering manifested itself as a strong diffuse scattering in diffraction patterns and as a similarity of low-wavenumber Raman spectra measured for different polarizations. Several domains were formed, though the single crystals remained intact. On releasing pressure, both the order in the crystal structure and the mono-domain single crystal were restored. Structural strain on increasing pressure prior to the phase transition was studied by single-crystal X-ray diffraction and Raman spectroscopy and compared with that on cooling, as well as with the pressure-induced strain of dl-serine, in which no pressure-induced disordering or structural transitions could be observed.
