Abstract

The reaction of hydrazine hydrate, N₂ H₄ ⋅ H₂ O, and SO₃ leads to hydrazine sulfonic acid (Pca2₁ , a=849.59(4) pm, b=482.18(2) pm, c=832.17(4) pm). Structure elucidation reveals the zwitter-anionic nature of the compound according to NH₃ NH(SO₃ ). With the barium salt Ba[NH₂ NH(SO₃ )]₂ (H₂ O), a first salt of hydrazine sulfonic acid has been prepared (P $\overline{1}$ , a=489.75(5) pm, b=737.52(7) pm, c=1317.4(1) pm, α=88.238(4)°, β=84.761(4)°, γ=79.701(4)°). The compounds were characterized by vibrational spectroscopy, DFT calculations and thermal analyses.

Keywords: hydrazine sulfonates; hydrazines; structural analyses; sulfonic acid; thermal analyses.
