LaP3O9·3H2O belongs to the REIIIP3O9·3H2O (RE = rare earth) polyphosphate family that crystallizes in space group P. In these cyclotriphosphates, the cyclic P3O93− anion has a planar configuration with 3/m internal symmetry. The La3+ cation, located on one of the axes, is ninefold-coordinated by six polyphosphate O atoms at a distance of 2.518 (2) Å and by three water O atoms at 2.584 (3) Å.
