Abstract: 

For the first time colourless single crystals of K2Na4[Be2O5] which are isotypic with K2Na4[Co2O5] [2] and Rb2Na4[Co2O5] have been prepared by heating e.g. a well ground mixture of K2O, Na2O and BeO (K:Na:Be = 2.2:4.4:2; 750-degrees-C; 21 d; Ni-tube). The crystal structure was solved by four-circle diffractometer data [Siemens AED 2; 389 I(o)(hkl); space group P4(2)/mnm; Z = 2; a = 595.17(4) pm, c = 1002.66(9) pm; R = 4.1%; R(W) = 2.3%].

Mean Fictive Ionic Radii, MEFIR, Effective Coordination Numbers, ECoN, the Madelung Part of Lattice Energy, MAPLE, and the charge distribution are calculated.
