Ammonium zinc phosphate, (NH₄)Zn(HPO₄)(H₂PO₄)

W. T. A. Harrison

Abstract: Ammonium zinc phosphate, (NH₄)Zn(HPO₄)(H₂PO₄), is built up from infinite 4-ring chains of vertex-sharing ZnO₄ and (H/H₂)PO₄ tetrahedra [d_av(Zn-O) = 1.943  (2)  Å and d_av(P-O) = 1.534  (2)  Å] crosslinked by ammonium cations. The intra-chain O-HO hydrogen bond appears to be essentially symmetric [d(OO) = 2.442  (3)  Å].
