چکیده
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 tightly bonded O atoms and four O atoms of one bridging and two terminal sulfato ligands, form zigzag chains parallel to [100]. All four Na(+) cations are situated between the anionic chains and have distorted octa-hedral coordination spheres.

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 ...

In the title one-dimensional coordination polymer, [Cd(SO(4))(C(5)H(8)N(2))(2)(H(2)O)(2)](n), the Cd(II) atom (site symmetry 2) is coordinated by two sulfate O atoms, two water mol-ecules and two 2-ethyl-imidazole ligands in a distorted cis-CdN(2)O(4) octa-hedral geometry. The water mol-ecules have a cis disposition. The bridging sulfate ions (site symmetry 2) link the Cd(II) ions into a polyme...
