چکیده
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 coordinated by eight O atoms, whereas the three other Rb atoms are coordinated by nine O atoms from sulfate and oxide groups, leading to distorted [RbO(x)] polyhedra.

In the centrosymmetric binuclear title molecule, [Co(2)(SO(4))(2)(C(8)H(7)N(3))(4)], the Co(II) ion is coordinated by two N,N'-bidentate 3-(2-pyrid-yl)pyrazole ligands and two sulfate ions, generating a distorted cis-CoO(2)N(4) octa-hedral geometry for the metal atom. The dihedral angles between the pyridine and pyrazole rings in the two ligands are 10.5 (2) and 7.38 (19)°. The bridging sulfate...
