Abstract
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) A, β = 92.37(1)°; V = 341.97(1) A3). 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).
