Abstract
By incorporation of the largest-electronegativity
F atoms into borate, two novel halogen-containing borates, Li<sub>6</sub>RbB<sub>2</sub>O<sub>6</sub>F and K<sub>3</sub>B<sub>3</sub>O<sub>3</sub>F<sub>6</sub>, have been synthesized. Interestingly,
Li<sub>6</sub>RbB<sub>2</sub>O<sub>6</sub>F is the first borate fluoride
in alkali-metal borate. Meanwhile, K<sub>3</sub>B<sub>3</sub>O<sub>3</sub>F<sub>6</sub> appears to be the first confirmed alkali-metal
fluoroborate crystal grown by a high-temperature solution in air
