Telluric acid and its salts mostly contain hexacoordinate tellurium.
2.
The two forms of telluric acid form " tellurate " salts containing the TeO and TeO anions, respectively.
3.
Telluric acid is often written with the formula H 2 TeO 4 ?H 2 O but is better described structurally as Te ( OH ) 6.
4.
The "'metatellurate "'anion has a chemical shift around 610 ppm when analyzed using 125 Te NMR at 25 �C at a frequency of 94.735 MHz and referenced externally against aqueous 1.0 M telluric acid.
