Refinement of F^2^ against ALL reflections. The weighted R-factor wR and
goodness of fit S are based on F^2^, conventional R-factors R are based
on F, with F set to zero for negative F^2^. The threshold expression of
F^2^ > 2sigma(F^2^) is used only for calculating R-factors(gt) etc. and is
not relevant to the choice of reflections for refinement. R-factors based
on F^2^ are statistically about twice as large as those based on F, and R-
factors based on ALL data will be even larger.
Three of four methyl groups of the (CH~3~)~4~N^+^ cation are disordered
into eight position (C8, C8') and refined with equal thermal factors
('eadp' command was used).
Hydrogen atoms of the water molecules are found in Fourier map and refined
isotropically with fixed thermal factors. Goodness volume is 1.285 deviating
slightly from expected 1.0 and shifts to smaller values with increasing wR2.
Short non-bonding inter D-H..H-D contacts are related
to disordered hydrogen atom.
The large second weight parameters might be attributed to the disordered
(CH~3~)~4~N^+^ cation and the disordered hydrogen atoms of the isolated
water molecules.

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.
