摘要
The new phase Li3Cu2SbO6, synthesised by solid state reaction at 1000 degrees C, is monoclinic, a=5.4659(1), b=8.7272(2), c=9.7807(3) Angstrom, beta=95.080(2)degrees, space group C2/c, and has a partially ordered rock salt structure related to the ordered structure of Li2TiO3 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 CuO6 octahedra consistent with magnetic susceptibility data that indicate paramagnetic Cu2+ ions. Li3Cu2SbO6 shows a low level of electronic conductivity. (C) 1997 Academic Press.
