Abstract

The EPR spectra of VO²⁺ complexes in Cs₅H₃(SO₄)₄ · H₂O have been investigated with the aim to study of SO^2- ₄ ions and H₂O molecules motions in the range (80–420) K. Results of EPR analyses presented, reveal gradual water molecules ‘freezing’ down to T_g = 260 K and an additional SO^2- ₄ unit freezing correlated to H₂O. It is shown that correlated interaction between SO^2- ₄ ions and water molecules leads to glassy-like freezing below T_g .
