Rubidium terbium polyphosphate

F. Khlissa and M. Férid

Abstract: The title compound, RbTb(PO3)4, belongs to type IV of the MIMIII(PO3)4 polyphosphate family. It was synthesized by the flux-growth method. In this condensed polyphosphate, PO4 tetrahedra share vertices to produce corrugated ribbons along the a-axis direction with a repeating unit of eight tetrahedra. Isolated TbO8 polyhedra link the phosphate anions into a three-dimensional framework with channels containing Rb+ cations.
