چکیده
The title compound, K(4)[Mo(VI)O(2)(SO(4))(3)], was precipitated from a melt of molybdenum(VI) oxide and potassium sulfate in potassium disulfate. The compound contains monomeric [Mo(VI)O(2)(SO(4))(3)](4-) anions, with the Mo(VI) atom, both oxide ligands, and the S atom and both ligating O atoms of the bidentate sulfate group lying on a crystallographic mirror plane. One of the potassium cations is nine-coordinate, while the other is eight-coordinate.

Single crystals of the title compound, {Na(4)[Mo(VI)O(2)(SO(4))(3)]}(n), were grown from a melt of MoO(3) and Na(2)SO(4) in Na(2)S(2)O(7). In contrast to the structure of the isoformular K compound, K(4)[Mo(VI)O(2)(SO(4))(3)], with its monomeric anion, this sodium analogue contains a polymeric anion of the type {[Mo(VI)O(2)(SO(4))(2)-μ-(SO(4))](4-)}(n). The Mo(VI) cations, surrounded by two tig...

The title compound, Rb(8)[W(2)O(4)(SO(4))(6)], was precipitated from a melt of tungsten(VI) oxide and rubidium sulfate in rubidium disulfate. The unit cell contains two discrete [{W(VI)O(2)(SO(4))(2)}(2)(μ-SO(4))(2)](8-) units connected by Rb-O coord-ination. The W atom is octahedrally surrounded by two oxide ligands, two terminal sulfate ligands and two bridging sulfate groups. One Rb atom is ...

The Ce(IV) atom in the title salt, {(H(3)NCH(2)CH(2)CH(2)NH(3))(2)[Ce(SO(4))(4)(H(2)O)]·2H(2)O}(n), exists in a monocapped square-anti-prismatic coordination geometry. The water-coordinated metal atom is bonded to four sulfate ions; one of them is monodentate and two function in a chelating mode. The fourth is also chelating but it uses one of the other two O atoms to bind to an adjacent metal ...

The asymmetric unit of the title compound, [Mn(2)(SO(4))(2)(C(6)H(5)NO(2))(2)(H(2)O)(6)], comprises half of a centrosymmetric dimer. The Mn(II) atom is coordinated by two O atoms of the monodentate carboxyl-ate ligand, an O atom of the sulfate anion in axial position and three water mol-ecules in a distorted octa-hedral geometry. In the crystal, mol-ecules are connected through N-H⋯O and O-H⋯O ...
