英文摘要The crystal structure of amarillite, NaFe(SO4)(2)(H2O)(6), was redetermined from a single crystal from Xitieshan, Qinghai Province, China. In complement to previous work, all non-H atoms were refined with anisotropic displacement parameters and H-atoms were located by difference Fourier methods and refined from X-ray diffraction data. The structure can be formally described by octahedral-tetrahedral "sheets" of corner-sharing [NaO4(H2O)(2)] octahedra and (SO4) tetrahedra, which constitute a structural sheet with composition [Na(SO4)(2)(H2O)(2)](3-)extending parallel to (001). The resultant sheets are held together by interstitial Fe3+ cations and hydrogen bonds. The [NaO4(H2O)(2)] octahedra donate four hydrogen bonds to the oxygen atoms of neighboring (SO4) tetrahedra, thus strengthening connections in three dimensions. The interstitial [FeO2(H2O)(4)] octahedra are linked by eight hydrogen bonds to the vertices of the adjacent octahedral-tetrahedral sheets, further stabilizing the crystal structure of amarillite. The FTIR spectrum of amarillite shows a strong absorption between 3000 cm(-1) and 3500 cm(-1) with maxima at similar to 3110 m(-1) and similar to 3442 cm(-1), which is in accordance with the O-H center dot center dot center dot O distances derived from structure data.
