Abstract
Single crystals of the spinel-type LiTi{sub 2}O{sub 4} (Cubic, Fd3m, a = 8.4095(12) {angstrom}) have been prepared by the reaction of lithium metal and TiO{sub 2} at 1373 K in a sealed iron vessel. The structure refinement by a single crystal X-ray diffraction study confirmed a normal spinel cation distribution; the lithium cations are located at the tetrahedral 8a sites, the titanium cations occupy the octahedral 16d sites, and the oxygen parameter u = 0.2622(4) with the final R = 3.8% (R{sub w} = 2.7%) for 60 independent observed reflections. The octahedral Ti-O distance is 2.005(3) {angstrom}, and the tetrahedral Li-O distance is 1.999(3) {angstrom}. The superconductivity for the crystals was observed by the magnetization measurements.
