Abstract: The crystal structure of cerium catena-polyphosphate, CeP3O9, is isotypic with the previously reported structures of La, Pr, Nd and Gd C-type polyphosphates. The absolute configuration of CeP3O9 was determined reliably. The structure contains helical polyphosphate chains with a period of six tetrahedra running along the c axis, and the Ce cation is in an eightfold coordination by terminal O atoms of the polyphosphate chains. Ce, one P and one O atom are located on twofold rotation axes.
