New acyclic monosubstituted aryl cobaltocenium derivatives, functionalised with additional hydrogen-bonding amine groups have been prepared.Quantitative investigation of the anion-binding properties by 1H NMR spectroscopy and electrochemical methods shows enhanced binding believed to be due to amine group participation in hydrogen bonding.Similar recognition studies on 1,1'-bis-substituted aryl cobaltocenium analogues indicate an order of magnitude selectivity for the dihydrogenphosphate anion over simple halide anions.The importance of hydrogen bonding is also illustrated by the first single-crystal structure showing the anion complex of a cobaltocenium recetptor.
