(NH4)2[Co(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[Co(H2O)6]3(HPO3)4 is composed of the units [Co(H2O)6]2+, (HPO3)2- and NH4+, which inter­act via an intricate network of hydrogen bonds. One of the Co atoms is located at a site of 2/m symmetry, whereas the other central atoms, viz. the second Co, the two P and ammonium N atom, are located at sites of m symmetry.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors are based on F, with F set to zero for negative F2. The threshold expression of F2 > n*σ(F2) is used only for calculating R-factors etc. and is not relevant to the choice of reflections for refinement.

The hydrogen atoms were localized from the difference Fourier map. Their coordinates were refined independently. The O—H distances were restrained to 0.82 Å with σ 0.01. The N—H distances were restrained to 0.87 Å with σ 0.01. The isotropic temperature parameters of hydrogen atoms were calculated as 1.2*Ueq of the parent atom.

The program used for refinement, JANA2000, uses the weighting scheme based on the experimental expectations, see _refine_ls_weighting_details, that does not force S to be one. Therefore the values of S are usually larger then the ones from the SHELX program.
