Figure 2
Part of the crystal structure of the title compound, showing the formation of hydrogen-bonded C(8) chains along [010]. Atoms marked with an asterisk (*) or a prime (′) are at the symmetry positions (−x, 1 − y, −z) and (x, y − 1, z), respectively. The two 1,2,3,5-tetra­methyl-4-nitro­pyrazolium cations have been omitted for clarity, as have all H atoms, except those of the (H5O2)+ unit, which are shown as circles of arbitrary radii. Displacement ellipsoids are drawn at the 30% probability level.
