Abstract: 

Rb2TiO3 [3], parent type of the oxides K2CoO3, Rb2CoO3 and Cs2CoO3 [4], colourless crystals, needles, was newly obtained by heating a well grounded mixture of the binary oxides RbO0.98, RbO0.52, Ti2O3 (molar ratio = 2.4:6.2:1.0) 41 d at 780 degrees C in Ni-Tubes.

The first structure determination by using four-circle diffractometer data (Siemens AED2, 5366 I-c(hkl), MoK alpha) leads to the a residual-values R = 7.9% and Rw = 3.7%. Lattice constants (orthorhombic, Cmca, Z = 8, Guinier-Simon-data, CuK alpha(1)): a = 596.5(1) pm, b = 1185.2(1)pm, c = 1326.6(1)pm (additional data see text). The structure determination 1974 by filmdata is confirmed.

The Madelung Part of Lattice Energy (MAPLE), Effective Coordination Numbers (ECoN), Mean Fictive Ionic Radii (MEFIR) and the Charge Distribution in Solids (CHARDI) are calculated and discussed.
