Ditellurium decafluoride
Ditellurium decafluoride was widely reported in the literature but what was believed to be Te2F10 has been shown to be bis oxide, F5TeOTeF5. An account as to how this error occurred was made by P. M. Watkins.
If it existed, it would be valence isoelectronic with disulfur decafluoride, and have a similar structure.
