Preparation and X-ray structures of selected aminium thiosulfates

Abstract

Various types of aminium thiosulfates (1–6), including hydrates and mixed salts, have been obtained by the reaction of ammonium thiosulfate with amines. Tertbutylamine, cyclo-hexylamine and 1,6-diaminohexane gave crystals of (t-BuNH3)2S2O3·H2O (1), (c-C6H11NH3)2S2O3 (3) and {(NH4)2(H3NC6H12NH3)(S2O3)2} (6), respectively, which were investigated by X-ray structural analysis. Extensive hydrogen bonding of the N-H…O and N-H…S type is responsible for formation of alternating hydrophilic and hydrophobic layers in the solid-state. In the case of (1), the layers are separated by strata of weak van der Waals interactions, while (3) consists of hydrogen-bonding stabilized rods along the b direction. The structure of (6) contains 3D covalent bonding plus hydrogen bonding networks with no separable substructures. Solubility and thermal decomposition are also briefly discussed.
