Cover Story: The Hydrated KNbWO6 pyrochlore contains a main covalent framework of (NbV,WVI)O6 octahedra sharing vertices (in green), forming large cavities wherein K, H, and O’ are distributed at 32e, 96g, and 32e Wyckoff sites, respectively. Detail: A2O’sub-lattice of K and water molecules are highlighted as purple tetrahedra. Only ¼ of the vertices are actually occupied by K atoms (some atoms are hidden for the sake of clarity).
