Abstract: 
The new oxide Rb3Na[TiO4], platelike colourless crystals, was obtained by heating a well grounded mixture of the binary oxides in Ni-tubes. Therewith the oxides RbO0.52, NaO1.03, Ti2O3 (Rb:Na:Ti = 2.8:2.5:1.0) were heated for 26 d at 1000 degrees C. Rb3Na[TiO4] (monoclinic, P2(1)/c) is ''isostructural'' with Rb3Na[PbO4] [2] lattice constants: a = 1076.3(3) pm, b = 638.8(4) pm, c = 1088.9(7) pm, beta = 112.83(12)degrees; four-circle diffractometer data, Z = 4). The structure was determinated by using four-circle diffractometer data (Siemens AED2, 6683 I-o(hkl), , R = 6.2%, R(w) = 3.8%, additional data see text). The Madelung Part of Lattice Energy (MAPLE), Effective Coordination Numbers (ECoN), Mean Fictive Ionic Radii (MEFIR) and the Charge Distribution in Solids are calculated and discussed.
