Lithium bis(2-methyllactato)borate monohydrate
The title compound {systematic name: poly[[aqua-lithium]-μ-3,3,8,8-tetra-methyl-1,4,6,9-tetra-oxa-5λ(4)-borataspiro-[4.4]nonane-2,7-dione]}, [Li(C(8)H(12)BO(6))(H(2)O)](n) (LiBMLB), forms a 12-membered macrocycle, which lies across a crystallographic inversion center. The lithium cations are pseudo-tetra-hedrally coordinated by three methyl-lactate ligands and a water mol-ecule. The asymmetric ...
متن کاملDoped Zinc Lithium Bismuth Borate Glasses
Zinc lithium bismuth borate glasses containing Er in (25x): Bi2O3:20Li2O:20ZnO: 35B2O3:xEr2O3 (where x=1, 1.5,2 mol %) have been prepared by melt-quenching method. The amorphous nature of the glasses was confirmed by x-ray diffraction studies. Optical absorption and fluorescence spectra were recorded at room temperature for all glass samples. Judd-Ofelt intensity parameters Ωλ (λ=2, 4, 6) are e...
متن کاملLithium difluoro(oxalato)borate tetramethylene sulfone disolvate
The title compound, Li(+)·C(2)BF(2)O(4) (-)·2C(4)H(8)O(2)S, is a dimeric species, which resides across a crystallographic inversion center. The dimers form eight-membered rings containing two Li(+) cations, which are joined by O(2)S sulfone linkages. The Li(+) cations are ligated by four O atoms from the anions and solvent mol-ecules, forming a pseudo-tetra-hedral geometry. The exocyclic coordi...
متن کاملStructural Characterization of fly ash doped lithium borate Glasses
Lithium borate glasses with fixed alkali content of 10 Mole % and different modifiers have been prepared. To compare the role of fly ash as a glass modifier the content of glass modifier PbO, Al2O3 have been kept same to 5 mole %. To investigate the structure FTIR and UV-VIS spectra of prepared samples have been taken. From optical data optical band gap and cutoff wavelength have been calculate...
متن کاملSynthesis and Characterization of Lithium Borate Glasses Containing Bismuth
A lithium bismuth borate glass system is prepared by the conventional melt quenching technique. The Powder X-Ray diffraction analysis of the prepared samples confirms the amorphous nature of the samples. The density and molar volume studies report the change of structure with the increase of bismuth content. The FTIR analysis of the samples revealed that the network structure of the prepared sa...
