Hydrated vanadium oxides containing alkali ions were prepared by the hydrothermal treatment of VOSO 4 aqueous solutions. The products adopted layered structures with a general composition of A 0.3 V 2 O 5 •nH 2 O (A=Na, K, Rb, Cs and NH 4 ). The layer spacings were around 11 A. They were almost unchanged for the compounds of different alkali ions. The layered structures are considered to be composed of the V 2 O 5 layers intercalated with water molecules and alkali ions. Dehydration by heating or evacuation caused transitions into the phases where the layer spacings contracted by 1 to 2 A leading to the values proportional to the size of alkali ions
