Cobaltoceniumylamido)pyridinium hexafluoridophosphate

The title compound, [Co(C5H5)(C10H9N2)]PF6, was synthesized from deproton­ated 1-amino­pyridinium iodide, followed by microwave-assisted nucleophilic aromatic substitution of iodo-cobaltocenium iodide. After anion exchange with potassium hexa­fluorido­phosphate, the title compound crystallizes as orange prisms in the space group Pc. This very stable pyridine nitrene adduct is the first example of a cobaltocenium derivative, formally containing a nitrene nitro­gen species.
