H. Ettis, H. Naïli and T. Mhiri

Abstract: Single crystals of rubidium gadolinium polyphosphate were grown from a polyphosphate flux. The structure of the title compound is isotypic with CsGd(PO3)4 and consists of helical polyphosphate chains running along the [101] direction with a period of eight PO4 tetrahedra. These polyphosphate chains are connected by isolated GdO8 dodecahedra and irregularly shaped RbO11 polyhedra, forming a three-dimensional framework.
