Borotellurites

Borotellurites are chemical mixed anion compounds that contain any kind of borate and tellurite ions bound together via oxygen.

They are distinct from borotellurates in which tellurium is in +6 oxidation state.

There are also analogous boroselenites, with selenium instead of tellurium, and borosulfates containing sulfur.

Borotellurites are colourless.
