| Abstract: | Two novel hydrated borates were synthesized under mild solvothermal conditions. One is hydrated rubidium borate, Rb2B7O9(OH)5, which contains the first example of the isolated chain heptaborate anion, B7O9(OH)5]2-. The other is hydrated diethylenetriamine borate, (C4H15N3)]2B14O20(OH)6], which contains the first example of the largest isolated ring tetradecaborate anion, B14O20(OH)6]4-. |
