[Ni(C 10 H 8 N 2 ) · 4 H 2 O]SO 4 · 2 H 2 O, Mr = 418.7, monoclinic, P 1 , a = 7.781(3), b = 9.421(3), c = 11.457(4) Å, α = 87.54(2)º, β = 96.40(2)º, γ = 102.58(2)º, ν = 814.5 Å, D x = 1.26 g/cm 3 , Z = 2, (MoKx) = 0.71073 Å, μ = 7.0 cm −1 : T = 23 °C, R = 0.047 for 2139 reflections having intensities greater than 36. The structure was solved using the Patterson heavy‐atom method and the remaining atoms were located in succeeding difference Fourier syntheses. The structure was then refined by full matrix least‐squares using anisotropic temperature factors. Hydrogen atoms were located and their positions and isotropic parameters were refined.
