The Crystal Structure of Disodium Phosphonate, Na2HPO3

Anhydrous disodium phosphonate, Na2HPO3, was prepared by dehydration of its pentahydrate. The crystal structure of Na2HPO3 was solved from high resolution X‐ray powder diffraction data (P21/n; Z = 4; a = 9.6987(1), b = 6.9795(1), c = 5.0561(1) Å, β = 92.37(1)°; V = 341.97(1) Å3).

Description
Summary:Anhydrous disodium phosphonate, Na2HPO3, was prepared by dehydration of its pentahydrate. The crystal structure of Na2HPO3 was solved from high resolution X‐ray powder diffraction data (P21/n; Z = 4; a = 9.6987(1), b = 6.9795(1), c = 5.0561(1) Å, β = 92.37(1)°; V = 341.97(1) Å3). The crystal structure consists of two types of sodium‐oxygen polyhedra, which are connected via common edges and vertices forming layers perpendicular to [100]. These Na(1)‐ and Na(2)‐layers are interlinked via common edges, forming in a 3D‐framework. The resulting topology is providing oxygen arrangements that please the coordinative requirement of phosphorus(III).
