摘要The structure of aqueous lithium tetraborate solutions was investigated by species distribution calculation and synchrotron X-ray scattering. It shows that the dominant species in supersaturated solution at 298.15 K is B4O5(OH) (4) (2-) and the minor species are B3O3(OH) (5) (2-) , B3O3(OH) (4) (-) and B(OH)(3). The 'intramolecular' structural parameters of B4O5(OH) (4) (2-) , such as bond length and coordination number, were gives out using density function theory calculation. X-ray scattering study shows that the distance Li-O(H2O)(I) of [Li(H2O)(4)](+) is about 0.1983 nm with the coordination number(CN) 4 in tetrahedral configuration. The B-O(H2O) distance in hydrated anion B4O5(OH)(4)(OH2) (8) (2-) is 0.3662 nm with the CN 12. The Li+-B distance is about 0.3364 nm with a coordination number similar to 1.0. The temperature effect on solution structure was also discussed.
