The water molecules O2W, O3W O4W and O5W are each disordered
equally over two orientations: each component was therefore
refined isotropically. O1WA and O1WB are disordered unequally
over two orientations with occupancies of 0.3 and 0.7 and
were also refined isotropically.

Appromimately 45% of the unit cell volume comprises a large region of
disordered solvent which could not be modelled as discrete atomic sites.
We used PLATON SQUEEZE to calculate the contribution to the diffraction
from the solvent region and thereby produced at set of solvent-free diffraction
intensities. SQUEEZE estimated a total count of 638 electrons per unit cell,
which were assigned to be 21 water molecules and 3.5 DMF molecules per unit
cell. The final formula was calculated considering elemental analysis results.

All esds (except the esd in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell esds are taken
into account individually in the estimation of esds in distances, angles
and torsion angles; correlations between esds in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell esds is used for estimating esds involving l.s. planes.

Atoms C3 and C3A are each disordered over two equally-occupied sites,
The disorder components were therefore refined isotropically.

;
Approximately 54% of the unit cell comprises a large region of
disordered solvent which could not be modelled as discrete atomic sites.
We employed PLATON SQUEEZE to calculate the contribution to the diffraction
for the solvent region and therefore produced a set of solvent-free diffraction
intensities. SQUEEZE estimated a total of 468 electrones per unit cell,
which are assigned to be 26 water molecules per unit cell. The final formula
was calculated considering elemental analysis results.

All esds (except the esd in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell esds are taken
into account individually in the estimation of esds in distances, angles
and torsion angles; correlations between esds in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell esds is used for estimating esds involving l.s. planes.

Appromimately 25% of the unit cell volume comprises a large region of
disordered solvent which could not be modelled as discrete atomic sites.
We used PLATON SQUEEZE to calculate the contribution to the diffraction
from the solvent region and thereby produced at set of solvent-free diffraction
intensities. SQUEEZE estimated a total count of 95 electrons per unit cell,
which were assigned to be 5 water molecules per unit cell. The final formula
was calculated considering elemental analysis results.
O-bound H atoms were not located but are included in the formula.
