Synthesis, Characterization and Structure Determination of a Three-Dimensional
Hydrated Potassium Zinc Divanadate: K[Zn2.5V2O7(OH)2]·H2O. — The title compound is prepared hydrothermally from an aq. solution of ZnCl2, V 2O5, and KOH
(1:1:4, 170 °C, autoclave, 21 h). The structure of K[Zn2.5V2O7(OH)2]·H2O is determined by Rietveld refinement of powder XRD data (orthorhombic, space group Pnnm,
Z = 4). The structure consists of interrupted and lacunary oxohydroxo zinc layers which
are bridged by divanadate groups to form a three-dimensional framework. The potassium cations and the water molecules occupy the channels between the bridged layers.
