Ammonium zinc hydrogenphosphite hydrate, (NH4)2Zn5(HPO3)6·4H2O

L. E. Gordon and W. T. A. Harrison

Abstract: The title compound contains HPO3 pseudo-pyramids [dav(P-O) = 1.516  (2)  Å], ZnO4 tetrahedra [dav(Zn-O) = 1.939  (2)  Å], and trans-ZnO2(H2O)4 octahedra. These building units link together by way of Zn-O-P bridges [[theta]av = 128.1°], resulting in a layered structure.
