The Crystal Structure of Ferrinatrite, Na3(H2O)3[Fe(SO4)3] and Its Relationship to Maus's Salt, (H3O)2K2{K0.5(H2O)0.5}6[Fe3O(H2O)3(SO46](OH)2

摘要: Ferrinatrite crystallizes in space group P, with a= 15· 566 (5), c= 8· 69 (1) Å, and Z= 6. The crystal structure was solved by three-dimensional Patterson and Fourier syntheses, and refined by least squares employing 2378 independent reflexions to a final R value of 0· 068. The iron ions occupy special positions and are surrounded octahedrally by oxygen atoms. Fe3+ O6 octahedra and SO4, tetrahedra are linked together to form infinite chains of Fe-OS linkages in the [0001] direction. These chains are linked to each other by [NaO5 (H2O) 2] …
