| Abstract: It is reported in this paper for the indirect electrosynthesis of a mixed ferrate(VI) crystal, K3Na(FeO4)2, with a comparatively high purity and its crystal structure is investigated in detail by powders XRD structure analysis. Its chemical formula is ascertained by EDX and AAS. The structure analysis showed that the crystal of K3Na(FeO4)2 is of hexagonal unit cell, space group P3m1(164), Z=1, 6 atoms of O are located at 6(i) Wyckoff Sites, 2 atoms of O, Fe and K at 2(d), respectively, 1 atom of K and Na at 1(b) and 1(a), respectively. Cell parameters a=0.583 3(1) nm, c=0.755 9(1) nm，D=2.824 g·cm-3. And all inter-atomic distances of K3Na(FeO4)2 are obtained. |
