From Wikipedia, the free encyclopedia
The boroselenites are heteropoly anion chemical compounds containing
selenite and
borate groups linked by common oxygen atoms. They are not to be confused with the
boroselenates with have a higher
oxidation state for
selenium , and extra
oxygen . If selenium is replaced by sulfur, it would be a
borosulfite . Boroselenites are distinct from
selenoborates in which selenium replaces oxygen in borate, or
perselenoborates which contain Se-Se bonds as well as Se-B bonds. The metal boroselenites were only discovered in 2012.
