摘要：

Black single crystals of Li0.5TiO2 were synthesized by the reaction of lithium metal and titanium dioxide at 1473 K. It crystallizes in the orthorhombic ramsdellite-type structure, space group Pbnm with a = 5.0356(6), b = 9.6377(8), c = 2.9484(7) angstrom, V = 143.09(4) angstrom3, and Z = 4. The structure was determined from a single-crystal X-ray study and refined to the conventional values R = 0.038 and wR =0.046 for 744 independent reflections. The distorted octahedral sites are occupied only by Ti atoms, and a Li atom is located at one tetrahedral tunnel site with the occupancy factor of 0.45(2). (C) 1994 Academic Press, Inc.
