The fluoro complex of tellurium with pyridine, [C5HsNH]TeF5, has been obtained22 as a pale green solid by treatment of the pyridine complex TeF4-py with aqueous hydrofluoric acid, whilst a white modification has been reported18 to be isolated from a mixture of tellurium dioxide and pyridine in hydrofluoric acid. 

The reaction of tellurium dioxide, vaporized at 0.0001 torr and collected in a diethyl ether matrix at — 196°, with a solution of cycloheptatrienyldicarbonylmethylmolybdenum in tetrahydrofuran at — 78° under an argon atmosphere produced, after four weeks, cycloheptatrienyldicarbonyl(methanetellurinato)molybdenum in 6% yield3 via insertion of tellurium dioxide into the Mo-mcthyl bond. The complex was postulated to have a Mo-Te bond3.
