Ditellurium decafluoride was widely reported in the literature but what was believed to be Te<sub>2</sub>F<sub>10</sub> has been shown to be teflic anhydride, F<sub>5</sub>TeOTeF<sub>5</sub>. 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.
