Intercalation compounds HxVOPO4 . yH(2)O (x = 0.3-1.0; y = 2.0-3.6) an
d KxVOPO4 . yH(2)O (x = 0.2-0.98; y = 1) were prepared by redox interc
alation of VOPO4 . 2H(2)O with acetone solutions of hydroquinone and p
otassium iodide respectively. Time course of reactions, X-ray diffract
ion and ac conductivity of prepared compounds were studied. The decrea
se of conductivity with increasing content of guest was observed. The
activation energy of conductivity of HxVOPO4 . yH(2)O was calculated f
rom the Arrhenius plot. The content of interlayer water increases duri
ng intercalation of hydronium ions as it was determined by DTA.
