摘要
本文采用间接法电合成出较高纯度的复盐K3Na(FeO4)2晶体,用粉末XRD结构分析法对其晶体结构作了详细研究。用EDX和AAS确认了其化学式。结构分析表明,K3Na(FeO4)2晶体属三方晶系,具有六方晶胞,空间群为P3m1(No.164),Z=1,晶胞中有6个O位于6(i)位,O,Fe和K各自有2个位于2(d)位,1个K和Na分别位于1(b)位和1(a)位,晶胞参数a=0.5833(1)nm,c=0.7559(1)nm,D=2.824g·cm-3。同时晶胞中各原子间化学键键长得到确定。
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 P3^-ml （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.
