Crystal structure and phonon properties of noncentrosymmetric LiNaB4O7

Polarized Raman and IR spectra of non‐centrosymmetric PbB4O7 single crystal

“…5 Therefore, the assignment of the vibrational bands to the respective normal modes can be made on the nomenclature commonly accepted for other borates (see Ref. 15 and references therein). The obtained spectra are clearly different from those of Li 2 B 4 O 7 , LiNaB 4 O 7 and similar crystals where the triangularly coordinated boron appears.…”

“…The structure of this tetraborate differs from those of lithium, mixed lithium-sodium, lithium-potassium and lithium-rubidium derivatives, which leads to changes in the phonon properties. 15 In particular, whereas the above-mentioned crystals are composed of both BO 3 …”

Structural, electronic properties and charge density distribution of the LiNaB4O7: Theory and experiment

“…Although crystal structure of this compound has been previously determined [26], however, one of the lattice constants given by Maczka et al [26] is wrong and the CIF file deposited in ICSD is also incorrect. Also Kityk et al [27], have reported the growth of this crystal.…”

Electrical transport properties of 0.5Li2O–0.5M2O–2B2O3 (M=Li, Na and K) glasses

“…Borate based compounds have attained importance mainly because of their nonlinear optical properties particularly in generating visible and UV light apart from their high laser damage threshold and wide optical transmission window. Alkali and mixed alkali borates such as Li 2 B 4 O 7 [4], LiNaB 4 O 7 [5] and LiKB 4 O 7 [6] have been reported to be promising for nonlinear optical applications. Li 2 B 4 O 7 crystal belongs to the space group I4 1 cd whereas the other two crystallize in orthorhombic space groups (LiNaB 4 O 7 in Fdd2 and LiKB 4 O 7 in P2 1 2 1 2 1 space groups).…”
