Abstract: 
By heating a well ground mixture of the binary oxides RbO0.59, KO0.55 and GeO2[Rb:K:Ge = 3.1:2.8:2; Ni-tube; 550-degrees-C (27d) and 450-degrees-C (22d)] colourless single crystals of Rb2K2[(GeO3)2] were obtained for the first time: space group Pnma with a = 1322.51(14) pm, b = 557.25(5)pm, c = 1155.09(5)pm. The structure was determined by four-circle diffractometer data [Mo-K(alphaBAR), 1311 from 1362 I0(hkl), R = 4.0%, R(w) = 2.6%]. The Madelung Part of Lattice Energy, MAPLE, and the Effective Coordination Numbers, ECoN, the latter via Mean Fictive Ionic Radii, MEFIR, have been calculated.
