The types, structures, and compositions of oxychloride groups present in the melt were established. It was found that BaO dissolution proceeded according to the reaction BaO (s) + [BaCl6] 4– (soln.) →[Ba2OCl6]4– (soln.) and was accompanied by the appearance of [Ba2OCl6] 4– groups (D3d symmetry) of a mixed oxychloride composition |
