Tellurate

In the naming of inorganic compounds it is a suffix that indicates a polyatomic anion with a central tellurium atom.

[7] The E0 or standard reduction potential value is significant as it gives an indication of the strength of the tellurate ion as an oxidizing agent.

[11] Other compounds whose stoichiometry suggests the presence of TeO4−5 may contain either the dimeric Te2O8−10 made up of two edge-sharing {TeO6} as in Li4TeO5[3] and Ag4TeO5[12] or corner-sharing {TeO6} octahedra as in Hg2TeO5.

[3] A similar hydroxy-oxy anion, Te2O6(OH)4 is found in sodium potassium ditellurate(VI) hexahydrate, Na0.5K3.5Te2O6(OH)4·6H2O which contains pairs of edge sharing octahedra.

[20] The metatellurate anion has a chemical shift around 610 ppm when analyzed using 125Te NMR at 25 °C at a frequency of 94.735 MHz and referenced externally against aqueous 1.0 M telluric acid.
