Barium bromite, Ba(BrO2)2, is formally the barium salt of bromous acid. It was the first bromite to be isolated, as the monohydrate,[1][2] which is formed by the controlled disproportionation of barium hypobromite at pH 11–12 and 0 °C.[2][3][4] The anhydrous salt can be prepared by heating barium bromate to 250 °C in vacuo.[5]
