Abstract
The first example of a pseudo-bicyclic guanidinium ligand is reported. When bound to an anion, the N,N’-bis(2-pyridyl)guanidinium cation persistently adopts the planar α,α conformation featuring intramolecular N⋅⋅⋅H–N–H⋅⋅⋅N hydrogen bonds in the solid state, which facilitates crystallization of sulphate from aqueous mixtures of anions.
