Difference electron density maps revealed the presence of disordered 
lattice solvate molecules, which were ultimately modeled through the
use of the SQUEEZE subroutine of the PLATON software suite. PLATON 
Reference: P. v.d. Sluis & A.L. Spek. Acta Cryst. (1990), A46, 194. 
Two accessible voids per lattice were found, comprising a 
total volume of 209 \%A and contributing a total of 99 electrons. 
The voids were assigned to disordered 10 H2O, which 
contribute 10  x 10 = 100 electrons in one unit cell.
