Synthesis and Structure of N(Hydroxyethyl)ethylenediammonium Sulfite Monohydrate

Abstract

A reaction between sulfur(IV) oxide and aqueous N(2hydroxyethyl)ethylenediamine yields onium sulfite of composition (HOCH2CH2NH2CH2CH2NH3)SO3 ⋅ H2O, which has been characterized by Xray diffraction, IR spectroscopy, and mass spectrometry. The threedimensional structure of the salt is stabilized by numerous hydrogen bonds, such as NH⋅⋅⋅O and OH⋅⋅⋅O.
