two resting octahedral position of the Zr(IV) atoms are occupied by two different dihydrogen phosphate groups. The orthophosphate molecules are located alternatively above and below the ab main plane and the dihydrogen phosphates are in the layer edges crosslinked by two of their oxygen atoms to two different zirconium atoms. The remaining two hydroxyl groups of the dihydrogen phosphate are pointing toward the interlayer gallery forming a pocket where a hydrogen bond is formed with the interlayer water molecules. The basal interlayer distance for γ-Zirconium phosphate is 12.2 Å, and the area surrounding the dihydrogen phosphate on the surface of the layers is 35 Å2.
