Abstract: The reaction between sulfur(IV) oxide and an aqueous suspension of aminoguanidinium hydro carbonate yields (CN4H7)2SO3 ⋅ H2O, an “onium” sulfite, which has been characterized by X ray diffraction and IR spectroscopy and mass spectrometry. The structure of the salt is stabilized by numerous H bonds, such as NH⋅⋅⋅O, OH⋅⋅⋅O, and NH⋅⋅⋅N. The incorporation of pyramidal ions into the network of H bonds is accompanied by the lowering of their symmetry in comparison with C3v, thus complicating the IR spectra of the salt in the region where the vibrations of the anion appear.
