Figure 2
A view of the structure of (I[link]) at 292 K, projected along the monoclinic b axis. The structure at 150 K is virtually the same, except for the disorder of atoms H6O and H7O, which are involved in the symmetry-restricted O6⋯O6 and O7⋯O7 hydrogen bonds, respectively. The tetraethyl­ammonium cations are symbolized by large circles. The right-hand side of the picture shows the anionic chains only.
