The structure of (NH 4 ) 4 H 2 (SeO 4 ) 3 and (ND 4 ) 4 D 2 (SeO 4 ) 3 superionic crystals below 180 K determined by X-ray singlecrystal analysis is presented. The compounds have the following crystal data: (NH 4 ) 4 H 2 (SeO 4 ) 3 (T β«Ψβ¬ 140 K), triclinic, space group P-1, a β«Ψβ¬ 7.647(2) A s , b β«Ψ
The isopiestic method has been used to determine the osmotic coefficients of the binary solutions Cs 2 SeO 4 (aq) at T = 298.15 K from (1.090 to 4.591) mol β’ kg -1 . The molalities m of (m 1 Cs 2 SeO 4 + m 2 NiSeO 4 )(aq) have been investigated by physicochemical analysis. The crystallization of a n
At room temperature, the new compound K 2 SeO 4 ' Te(OH) 6 was synthesized from water solutions of H 6 TeO 6 /K 2 SeO 4 . The potassium selenate tellurate (KTSe), M m "480.81 g, possesses a monoclinic structure with Cc space group. The crystal and re5nement cell parameters are: a β«Ψβ¬ 11.552(2) A s ,
