Abstract:The crystal structure of the hexagonal phase KxVxMo1?xO3 (x = 0.13) has been determined by single crystal X-ray analysis. The space group is P63. The parameters are a = 10.481 Å and c = 3.701 Å. The structure is formed by triple chains of octahedra sharing corners and parallel to the Oz axis. Each triple chain shares edges with three other chains.Potassium is inserted in the large tunnels. The reliability factor is R = 0.045 on the base of 158 observed reflexions. The RbxVxMo1?xO3 and CsxVxMo1?xO3 phases (0.12 ? x ? 0.14) are isostructural with KxVxMo1?xO3.
