A new macrocyclic amide-substituted cobaltocenium receptor 1.1'-cobaltocenium hexafluorophosphate 2 has been prepared and its single-crystal X-ray structure determined.Proton NMR anion co-ordination studies revealed that 2 and other new acyclic cobaltocenium derivatives complex chloride and bromide anions with 1:1 stoichiometry.Comparative stability constant evaluations imply that the macrocyclic receptor 2 forms halide complexes of greatest thermodynamic stability, suggestive of a 'macrocyclic anion effect'.Cyclic voltammetric investigations showed the cobaltocenium receptors to electrochemically recognise halide anions.
