The polymeric ions B/sub 5/O/sub 6/(OH/sup -//sub 4/, B/sub 3/O/sub 3/(OH)/sup -//sub 4/, B/sub 4/O/sub 5/(OH)/sup 2 -//sub 4/, and B/sub 3/O/sub 3/F/sub 6//sup 3 -/ have been identified in solution and their regions of stability established. Comparisons of Raman spectra of the solutions with the spectra of solid reference materials containing the same structural entities, NaB/sub 5/O/sub 8/.5H/sub 2/O, orthorhombic metaboric acid (HBO/sub 2/)/sub 3/, Na/sub 2/B/sub 4/O/sub 7/.10H/sub 2/O, and Na/sub 3/B/sub 3/F/sub 6/O/sub 3/ were used to identify the ions. The charge on the polyborate ions was established on the basis of material and ionic balances. The hydrolytic behavior of Na/sub 3/B/sub 3/F/sub 6/O/sub 3/ was established. This compound is partially depolymerized into BF/sub 2/(OH)/sup -//sub 2/ ions which disproportionate into BF/sub 3/OH/sup -/, F/sup -/, and H/sub 3/BO/sub 3/. A new synthesis for Na/sub 3/B/sub 3/F/sub 6/O/sub 3/ was developed.
