The structure consists of alternating layers of [P3O9]3− groups, ErO8 dodecahedra, Na(1)O6 and Na(2)O7 polyhedra linked together by water molecules. The P3O9 rings are grouped along the c-axis in a P3O9-ErO8 arrangement thereby producing broad, hexagonal channels of diameter of 6.65Å with a side dimension of 3.907 Å. The absence of coincidences for the majority of the IR and Raman bands observed for the cyclotriphosphate salt is in accord with the centrosymmetric structure of the material. The vibrational spectra have been interpreted on the basis of factor group effects.
