Alkali metal cations (•) and water molecules (○) occupy nonframework sites in these structures, which were synthesized hydrothermally. References 1 M. Taramasso, G. Perego, B.

Intensities were measured on a SMART platform diffractometer equipped with a 1K CCD area detector using graphite-monochromated MoKα radiation at 20 °C. The structures was solved with direct methods and refined by using the SHELXTL program. All atom positions were refined anisotropically in the final refinements. The hydrogen atoms of the disordered water molecules were not located.
