In the commercially available title compound, C6H12O12·2H2O, the dodecahydroxycyclohexane molecule has an inversion center. The crystal packing is characterized by a strong O—H
O hydrogen bond involving the water molecules, and the dodecahydroxycyclohexane molecules are additionally linked by O—HO hydrogen bonds of the hydroxyl groups, resulting in the formation of a three-dimensional network.

The title compound, 2C5H6N+·TeF5−·0.5Te2F6O22−, contains two anions, [TeF5]− and [Te2O2F6]2−. The [Te2O2F6]2− anions are involved in HF/O bonding with the pyridinium cations. Crystallographically imposed inversion leads to molecular Cs symmetry for the [Te2O2F6]2− anions. Extended chains of inversion-related pyridinium cations are built up by π–π interactions.
