 Diffuse, disordered solvent molecules could not be adequately modeled.  The
 bypass procedure in Platon (Spek, 1990) was used to remove the electronic
 contribution from these solvents. The total potential solvent accessible void
 volume was 4045.0 Ang^3^ and the electron count / cell = 1865. As the exact
 solvent content is not known, the reported formula reflects only the atoms
 used in the refinement.
