 Highly disordered solvent was located in the structures.
 Reflection contributions from this solvent were removed
 using program SQUEEZE, which determined there to be 113 electrons
 in 452 \%A^3^ removed per unit cell. 
 One lithium atom was determined based on elemental analysis results,
 which could not be directly located from the difference Fourier maps. 
 Thus, the total number of electrons [113] in the void per unit cell, 
 which is attributed to one lithium atom and
 eleven disordered water molecules per molecule unit.
 Therefore, some reported items that derive from the molecular formula, 
 (e.g., F(000), density, etc.) are known to be incorrect.
