This compound don't exist today.
Francium is the most reactive of all the alkali metals, but its chemistry is totally unknown as it is extremely radioactive. Its most stable isotope decay in just 21,8 minutes. So no Francium compounds, as we know them, exist.
I realize this question was asked 11 years ago, but I would like to give it a shot.
My best guess would be FrβTe; FrβΊ being Francium's most stable state with a positive charge and TeβΊβ΄ being Tellurium's most common state. However, I am but a simple Y9 student with no GCSEs, so I may be incorrect.
This compound is not known; also the chemistry of francium is practically unknown.
