β¦ Synopsis
The new phase Li 3 Cu 2 SbO 6 , synthesised by solid state reaction at 1000 Β°C, is monoclinic, aβ«,)1(9564.5Ψβ¬ bβ«,)2(2727.8Ψβ¬ cβ«Ψβ¬ 9.7807(3) A s , β«,Β°)2(080.59Ψβ¬ space group C2/c, and has a partially ordered rock salt structure related to the ordered structure of Li 2 TiO 3 by additional cation order: Ti sites are occupied by Cu and Sb in ordered fashion; Li sites contain Li/Cu in two sets, but with nonstatistical occupancy, and Li. Bond lengths show a Jahn-Teller elongation of CuO 6 octahedra consistent with magnetic susceptibility data that indicate paramagnetic Cu 2Ψ ions. Li 3 Cu 2 SbO 6 shows a low level of electronic conductivity.
