Teflic acid is the chemical compound with the
The conjugate base of teflic acid is called the teflate anion, (not to be confused with triflate). Many teflates are known, examples being and the acid anhydride . Pyrolysis of the boron compound gives the dimer .
:
The teflate anion is known to resist oxidation. This property has allowed the preparation several highly unusual species such as the hexateflates (in which M = As, Sb, Bi). Xenon forms the

is related to orthotelluric acid, . Teflic acid has a slightly distorted octahedral geometry.
Preparation
Teflic acid was accidentally discovered by Engelbrecht and Sladky. Their synthesis did not yield the anticipated telluryl fluoride , but a mixture of volatile telluric compounds, ''i.e.'' :Engelbrecht, A.; Sladky, F.
