    Fluorine has 7 outer electrons, 2 of which are spent in bonding (sigma) to the 2 xenon atoms. That makes the number of electrons equal to 5 (2 pairs, 1 unpaired). So if FXe2 were to exist (and I am not saying it doesn't exist for I don't know myself) then it would have a funny geometry...2 sigma bonds, 2 lone pairs and 1 unpaired electron (counting basically).
