Complexation in the system K{sub 2}SeO{sub 4}-UO{sub 2}SeO{sub 4}-H{sub 2}O
Complexation in the system K{sub 2}SeO{sub 4}-UO{sub 2}SeO{sub 4}-H{sub 2}O at 25{degrees}C is studied by isothermal solubility. Congruently soluble K{sub 2}UO{sub 2}(SeO{sub 4}){sub 2}{center_dot}4H{sub 2}O (I) and incongruently soluble K{sub 2}(UO{sub 2}){sub 2}(SeO{sub 4}){sub 3}{center_dot}6H{sub 2}O (II) are observed. The unit-cell constants of I and II are determined from an X-ray diffraction investigation. For I, a = 12,969, b = 11.588, c = 8.533 {angstrom}, Z = 4, space group Pmmb. For II, a = 23.36, b = 6.784, c = 13.699 {angstrom}, {beta} = 104.42{degrees}, Z = 4, space group P2/m, P2, or Pm. Complexes I and II are representatives of the crystal-chemical groups AB{sup 2}{sub 2}M{sup 1} and A{sub 2}T{sup 3}{sub 3}M{sup 1}, respectively, of uranyl complexes.
