Structure determination of A₂M³⁺TaO₆ and A₂M³⁺NbO₆ ordered perovskites: octahedral tilting and pseudosymmetry

The room-temperature crystal structures of six A₂M³⁺M⁵⁺O₆ ordered perovskites have been determined from neutron and X-ray powder diffraction data. Ba₂YNbO₆ adopts the aristotype high-symmetry cubic structure (space group Fmm, Z = 4). The symmetries of the remaining five compounds were lowered by octahedral tilting distortions. Out-of-phase rotations of the octahedra about the c axis were observed in Sr₂CrTaO₆ and Sr₂GaTaO₆, which lowers the symmetry to tetragonal (space group = I4/m, Z = 2, Glazer tilt system = a⁰a⁰c^-). Octahedral tilting analogous to that seen in GdFeO₃ occurs in Sr₂ScNbO₆, Ca₂AlNbO₆ and Ca₂CrTaO₆, which lowers the symmetry to monoclinic (space group P2₁/n, Z = 2, Glazer tilt system = a^-a^-c⁺). The Sr₂MTaO₆ (M = Cr, Ga, Sc) compounds have unit-cell dimensions that are highly pseudo-cubic. Ca₂AlNbO₆ and Ca₂CrTaO₆ have unit-cell dimensions that are strongly pseudo-orthorhombic. This high degree of pseudosymmetry complicates the space-group assignment and structure determination. The space-group symmetries, unit-cell dimensions and cation ordering characteristics of an additional 13 compositions, as determined from X-ray powder diffraction data, are also reported. An analysis of the crystal structures of 32 A₂MTaO₆ and A₂MNbO₆ perovskites shows that in general the octahedral tilt system strongly correlates with the tolerance factor.
