X-ray powder diffraction study of La 2 LiTaO 6
2015
The structure of La 2 LiTaO 6 has been derived from the powder X-ray powder diffraction (XRD) data. La 2 LiTaO 6 is monoclinic with unit-cell parameters a = 5.621(1) A, b = 5.776(1) A, c = 7.954(2) A, β = 90.34(2)°, space group P 2 1 / n (14), and Z = 2. The structure of La 2 LiTaO 6 is an ordered perovskite with alternating Li and Ta octahedra. A new set of powder XRD data ( d -spacing and intensity listing) has been generated to replace entry 00-039-0897 within the Powder Diffraction File. The newly elucidated structural data for La 2 LiTaO 6 shall facilitate quantitative analysis of this impurity phase which is often observed during synthesis of the fast-ion conductor phase Li 5 La 3 Ta 2 O 12 .
