Na 9 [FeO 3 ][FeO 4 ]a Mixed Valent Oxoferrat(II, III) with Isolated [FeO 3 ] 4— — and [FeO 4 ] 5— Anions Na 9 [FeO 3 ][FeO 4 ] has been formed and obtained from a redox reaction between CdO and iron metal (reaction container) and Na 2 O in the presence of NaOH at 450 °C as orange‐red transparent single crystals. The crystal structure determination (IPDS data: Pca2 1 , a = 956.2(2) pm, b = 999.1(2) pm, c = 1032.3(2) pm, Z = 4, R all = 0.0455) reveals the presence of isolated complex anions, [FeO 3 ] 4— and [FeO 4 ] 5— .
