New metal oxides with doubles of tetrahedra as building units: Rb6[Tl2O6] and Cs6[In2O6]
Description
We prepared the hitherto unknown Rb6[Tl2O6] and Cs6[In2O6] by heating mixtures of Tl2O3 and RbO0.60 (Rb:Tl = 3.5:1) as well as In2O3 and CsO0.53 (Cs:In = 3.5:1) as single crystals [closed Ag-cylinder, 650 0C, 14 d]. The single crystals of Rb6[Tl2O6] are yellow, those of Cs6[In2O6] pale yellow, all transparent and rude. The new type of structure was elucidated by 4-circle-diffractometer (PW 1100) data. Rb6[Tl2O6]: P21/a; a = 1145.7(3), b = 713.3(1), c = 783.9(2) pm, β = 93.730 (2), Z = 2, Ag-K-α, 2100 out of 2531 I0(hkl), R = 9.6% and Rw = 8.9%. Cs6[In2O6]: P21/a; a = 1178.5(4), b = 730.7(2), c = 816.3(2) pm, β = 95.380 (3), Z = 2, Mo-K-α, 1584 out of 2032 I0(hkl), R = 9.25% and Rw = 8.44%. The Madelung Part of Lattice Energy, MAPLE, is calculated and discussed. (author)
