Borotellurites

From Wikipedia, the free encyclopedia

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.
