Abstract: 

Dark red-brown single-crystals of K2Na4[Fe2O5] were obtained for the first time by heating ''K3Na3CdO4'' at 500-degrees-C in closed Fe-cylinders. Determination and refinement of the crystal structure confirms the space group P4(2)/mnm (No. 136). Four-circle diffractometer data: MoKalphaBAR, 373 out of 373 I(o)(hkl); R = 5.3 %; R(w) = 4.6%; a = 645.94(5), c = 1 039.2(1) pm.

In contrast to the already known oxoferrates(II) with the ''Butterfly-Motiv'', Rb6[Fe2O5] and K6[Fe2O5] [1], we now found an isotypic structure for K2Na4[Fe2O5] with the oxocobaltates of Rb2Na4[Co2O5] and K2Na4[Co2O5] [2].
