Abstract The crystal structures of two hexammonium polymorphs, 1 and 2, and the ethane-1,2-diammonium, 3, salts of dinitramide have been determined. 1 crystallizes in the triclinic space group $${P\bar 1}$$ with cell dimensions a = 6.391(2), b = 7.5826(9), c = 10.828(1) Å, a = 77.58(1), β = 88.18 (2), γ = 87.54(2)°, 2 crystallizes in the monoclinic space group P21/c with cell dimensions a = 6.4893(3), b = 14.5149(8), c = 10.6557(4) Å, β = 94.300(4)°, and 3 crystallizes in the triclinic space group $${P\bar 1}$$ with cell dimensions a = 5.614(1), b = 6.867(2), c = 7.371(2) Å, α = 68.89(2), β = 89.00(2), γ = 78.90(2)°. The three structures all contain protonated amine cations which are involved in hydrogen bonding interactions with dinitramide anions.
