Abstract: 
For the first time Rb2K4Co2O5 was obtained by annealing intimate mixtures of the binary oxides as dark red single crystals (Rb:K:Co = 1.2:3.2:1; Ni-tube; 570-degrees-C; 20 d). Structure Refinement [fourcircle diffractometer data; PW 110; AgKBAR-alpha radiation; 401 of 607 I(o)(hkl); R = 9.9%; R(w) = 5.5%; space group P4(2)/mnm; Z = 2; a = 674,2(4), c = 1172,2(6) pm] confirms the isotypism to K2Na4Co2O5, Rb2Na4Co2O5 [2] and K2Na4Be2O5 [2]. The Madelung Part of Lattice Energy, MAPLE, Effektive Coordination Numbers, ECoN, these via Mean Fictive Ionic Radii, MEFIR, and the Charge Distribution, SIGMA-Q, were calculated. The isotypism of Rb2K4Co2O5 and Rb2Na4Co2O5 is compared graphically.
