Organically-Templated Zinc and Thorium Sulfates with Chain and Layered Structures

Abstract

Amine-templated zinc sulfates of the formulae, [Zn(SO4)(H2O)(2)(C10N2H8)] (1) and [C3N2H12][Zn(SO4)] (11) both with linear structures have been prepared under hydro/solvothermal conditions. Of these, I has the chain structure formed by ZnO(4)N(2)octahedra and SO4 tetrahedra, while It comprises ladders formed by corner-sharing four-membered rings. Amine-templated thorium sulfates of the formula [HN(CH2)(6)NH](2)[Th-2(SO4)(6)(H2O)2]-2H(2)O, (III) and [H2N(CH2)(4)NH2][Th-3(SO4)(7)(H2O)4(.)5H(2)O (IV) are also obtained under hydrothermal conditions. III has a sheet structure consisting of cages whereas IV has a two-dimensional structure derived from the connectivity of ladders.
