Abstract

The A2CuTiO6 (A = Y, Tb-Lu) series has been reinvestigated in light of the recent discovery of cation order in structurally similar La4Cu3MoO12 and La3Cu2VO9. The crystal structure has been determined by electron and powder x-ray diffraction. The phases crystallize in an hexagonal symmetry, space group P63cm with cell parameters a ≈ 6.2 Å; c ≈ 11.5 Å. In this series of compounds, the Cu(II) and Ti(IV) cations randomly occupy trigonal bipyramids which form layers separated by sevenfold coordinated A(III) cations. This series is isotypical with LuMnO3.
