Abstract: (NH4)2[Ni(H2O)6]3(HPO3)4 is a member of the isotypic (NH4)2[T(H2O)6]3(HPO3)4 family, where T = Co, Ni or Mg. The structure of (NH4)2[Ni(H2O)6]3(HPO3)4 is composed of the units [Ni(H2O)6]2+, (HPO3)2- and NH4+, which interact via an intricate network of hydrogen bonds. One of the Ni atoms is located at a site of 2/m symmetry, whereas the other central atoms, viz. the second Ni, the two P and ammonium N atom, are located at sites of m symmetry.
