La2LiMoO6

Structure and magnetic properties of theS=1geometrically frustrated double perovskitesLa2LiReO6

“…This compound was first reported to have an orthorhombic structure with cell parameters a = 5.577 ͑Å͒, b = 5.663 ͑Å͒, and c = 7.876 ͑Å͒ from x-ray powder diffraction. 5 On the contrary, two related compounds 13 have been reported as monoclinic, P2 1 / n, from neutron powder or single-crystal x-ray diffraction. From Shannon's ionic radii Re 5+ resides between Mo 5+ and Ru 5+ ͓Mo 5+ = 0.61 Å, Re 5+ = 0.58 Å, and Ru 5+ = 0.565 Å ͑Ref.…”

“…9 The unit-cell constants refined from the data collected at 300 K are a = 5.5939͑2͒ Å, b = 5.6924͑2͒ Å, c = 7.8803͑2͒ Å, and ␤ = 90.260͑3͒°. The overall refinement results are shown in Fig.…”

Interplay between humidity, temperature and electrical response of a conductivity sensor based on a La2LiNbO6 double perovskite

“…It belongs to the family of analogous phases La2LiMO6 (M= Mo, Re, Ta, Ir) and to the best of our knowledge it has not been reported before. 23,24 The perovskite here described was found previously as a secondary phase in the synthesis of the garnet-type solid electrolytes Li5La3Nb2O12. 25 Here we have prepared La2LiNbO6 as a single phase material and we have studied its structural features by powder X-ray and neutron diffraction and high resolution scanning transmission electron microscopy (STEM).…”
