;
Highly disordered water molecule was found 
during refinement. The located positions did not show good
convergence during refinement. Therefore
squeeze routine of PLATON was used to remove the scattering
contribution from the solvent molecule. Squeeze results are 
appended to the cif. A total of 20 electrons are removed
from the unit cell (Z = 4)which may correspond to one-fourth
water molecule in the asymmetric unit.
The atom removed through squeeze are not 
shown in the unit cell contents.
