The crystal structures of the two title tetracyanonickelate(II) salts of organic ammonium ions, (18-crown-6)-(2-hydroxyethylammonium) tetracyanonickelate(II), I, and 10-aminodecylammonium tetracyano nick-elate(II), II, have been analyzed. I crystallizes in the monoclinic space group P21/n with a = 10.458(2), b = 8.267(3), c = 24.045(2) Å, β = 94.09(1)°, V = 2074(1) Å3, Z = 2, R = 0.061 for 2274 reflections; II is triclinic P1 with a = 9.437(3), b = 10.094(3), c = 9.205(3)Å,a = 110.16(2), β = 112.72(3), γ = 69.16(2)°, V = 733.7(5) Å3 2=1, R = 0.040 including all the hydrogen atoms refined for 2724 reflections. The square planar tetracyanonickelate(II) anion is in a favourable position to form hydrogen bonds via N with the hydroxyl group in I and the ammonio group in II, respectively.
