Rubidium ytterbium(III) tetra-kis-(polyphosphate), RbYb(PO3)4, was synthesized by solid-state reaction. It adopts structure type IV of the MRE(PO3)4 (M = alkali metal and RE = rare earth metal) family of compounds. The structure is composed of a three-dimensional framework made up from double spiral polyphosphate chains parallel to [10-1] and irregular [YbO8] polyhedra. There are eight PO4 tetra-hedra in the repeat unit of the polyphosphate chains. The Rb(+) cation is located in channels extendi ...[more]
