چکیده
The title compound, sodium ammonium sulfate-telluric acid (1/1), Na(0.39)(NH(4))(1.61)SO(4)·Te(OH)(6), is isostructural with other solid solutions in the series M(1-x)(NH(4))(x)SO(4)·Te(OH)(6), where ammonium is partially replaced with an alkali metal (M = K, Rb or Cs). The structure is composed of planes of Te(OH)(6) octa-hedra alternating with planes of SO(4) tetra-hedra. The Na(+)/NH(4) (+) cations are statistically distributed over the same position and are located between the planes. The structure is stabilized by O-H⋯O and N-H⋯O hydrogen bonds between the telluric acid adducts and the O atoms of sulfate groups, and between the ammonium cations and O atoms, respectively. Both Te atoms lie on centres of symmetry.

Hydration of arsenic oxyacid species.
The bond distances in hydrated arsenic oxyacid species in aqueous solution have been studied by EXAFS spectroscopy and large angle X-ray scattering, LAXS. These results have been compared to structures in the solid state, as found in an extensive survey of available crystal structures. Protonated oxygen atoms can be distinguished with a longer As-O distance for both arsenic(V) and arsenic(III) ...

UraniumIV sulfate in an aqueous solution and the solid state has been investigated with extended X-ray absorption fine structure (EXAFS) and X-ray diffraction (XRD). The coordination polyhedron comprises monodentate sulfate, bidentate sulfate, and water molecules. The coordination modes of sulfate in solution have been determined from the U-S distances with EXAFS. The U-S distance of 3.67 +/- 0...
