borate sulfate

{{Short description|Mixed anion compound containing separate borate and sulfate anions}}

Borate sulfates are mixed anion compounds containing separate borate and sulfate anions. They are distinct from the borosulfates where the borate is linked to a sulfate via a common oxygen atom.
