The title compound, octacaesium pentadecairon decafluoride dodecaphosphate, was prepared by hydrothermal methods. The structure contains three types of Fe polyhedra (octahedra, tetrahedra and five-vertex polyhedra) which share vertices to form two-dimensional `branched' layers approximately parallel to the (120) plane. These layers are linked into a framework by PO4 tetrahedra. The Cs atoms occupy holes in the mixed Fe/P framework.
