Abstract: 
By heating a well grounded mixture of the binary oxides Rb2O, Na2O, Li2O, and TiO2 [Rb:Na:Li:Ti = 1.1:3.1:12.5:4.0; 780 degrees C, 41 d] we obtained RbNa3Li8{Li[TiO4]}(4) as colourless platelike crystals. This first titanate with ''stuffed pyrgoms'' is isostructural with RbNa3Li3{Li[SiO4]}(4), CsKNa2Li8{Li[SiO4]}(4) and CsKNaLi9{Li[SiO4]}(4) [2]. The compound crystallizes tetragonal I4/m with a = 1125.8(1)pm and c = 652.4(1) pm (Guinier-Simon-Data, Z = 2). The structure was determined by four-cyrcle-data (Siemens AED2, MoK ($) over bar alpha) and leds to the residual values R = 3.7% and R(w) = 3.1% (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 (CHARDI) are calculated and discussed.
