The Borate Minerals are minerals which contain a borate anion group. The borate (BO 3) units may be polymerised similar to the SiO 4 unit of the silicate mineral class. This results in B 2 O 5, B 3 O 6, B 2 O 4 anions as well as more complex structures which include hydroxide or halogen anions. [2] The [B(O,OH) 4] − anion exists as well.
A borate is any of a range of boron oxyanions, anions containing boron and oxygen, such as orthoborate BO 3− 3, metaborate BO − 2, or tetraborate B 4 O 2− 7; or any salt of such anions, such as sodium metaborate, Na + [BO 2] − and borax (Na +) 2 [B 4 O 7] 2−. The name also refers to esters of such anions, such as trimethyl borate B ...

The borate bromides are mixed anion compounds that contain borate and bromide anions. They are in the borate halide family of compounds which also includes borate fluorides , borate chlorides , and borate iodides .
Borate sulfides are chemical mixed anion compounds that contain any kind of borate and sulfide ions. They are distinct from thioborates in which sulfur atoms replace oxygen in borates. There are also analogous borate selenides , with selenium ions instead of sulfur.
The borotellurates are heteropoly anion compounds which have tellurate groups attached to boron atoms. The ratio of tellurate to borate reflects the degree of condensation. In [TeO 4 (BO 3) 2] 8-the anions are linked into a chain. [1] In [TeO 2 (BO 3) 4] 10− the structure is zero dimensional with isolated

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 ...
