organic compounds
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.
organic compounds
The crystal structure of Mes*TeI (Mes* = 2,4,6-tri-tert-butylphenyl), C18H29ITe, exhibits discrete molecules without TeI, TeTe or II intermolecular contacts. The compound was prepared by cleavage of its parent ditellane with iodine, and represents a kinetically stabilized arenetellurenyl iodide with a very bulky substituent. The molecule possesses an angular C—Te—I arrangement [95.75 (8)°] with a Te—I single bond [2.7181 (6) Å].
