Abstract The crystal structure of the title compound has been redetermined from three-dimensional neutron diffraction data with 511 reflections. Z = 4 in the monoclinic space group C2/c, with cell dimensions a = 1 248.3(6), b = 749.9(4), c = 720.8(3) pm, β = 91.21(2)°. The structure was refined by full-matrix least-squares in the centric space group C2/c to R 0.056. The nitrogen in the anion was found to be on a two-fold axis and surrounded tetrahedrally by two groups and two half hydrogen atoms. Refinement in the non-centric space C gave R 0.058, with the nitrogen trigonally surrounded by the trioxosulphates and one hydrogen atom. This model was rejected on the basis of Hamilton's significance test.
