Zur Synthese von Na3FeO3, einem ternären Oxoferrat(III) mit Kettenstruktur

Synthesis of Na3FeO3, a Ternary Oxoferrate(III) with a Chain Structure Na3FeO3 has been obtained from a redox reaction between CdO and iron metal in the presence of Na2O and Na2CO3 at 650 °C as amber colored transparent single crystals. The crystal structure determination (IPDS data: P21/n, a = 579.9(1) pm, b = 1265.9(2) pm, c = 582.8(1) pm, β = 116.02(2)°, Z = 4, Rall = 0.0576) reveals the presence of [FeO2O2/2] zig-zag-chains.
