چکیده انگلیسی
Single crystals of lanthanum lithium aluminum oxide, La2Li0.5Al0.5O4, were synthesized for the first time by a flux method at 773 K. The La2Li0.5Al0.5O4 single crystal is colorless, has an average size of 60 μm with a square platelet shape, and crystallizes in the tetragonal K2NiF4-type structure, space group I4/mmm with a = 3.7742(9) Å, c = 12.753(4) Å, V = 181.66(10) Å3, and Z = 2. The structure was determined using single-crystal X-ray diffraction data and refined to the conventional values R = 1.25% and wR = 1.28% for 524 observed reflections. The octahedral site was randomly occupied by Li and Al atoms. The corresponding polycrystalline sample was also prepared by a conventional solid-state reaction method at 1123 K.
