The new phase Li3Cu2SbO6, synthesised by solid state reaction at 1000°C, is monoclinic,a=5.4659(1),b=8.7272(2),c=9.7807(3) Å,β=95.080(2)°, space groupC2/c, and has a partially ordered rock salt structure related to the ordered structure of Li2TiO3by 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 CuO6octahedra consistent with magnetic susceptibility data that indicate paramagnetic Cu2+ions. Li3Cu2SbO6shows a low level of electronic conductivity.
