The title compound, [Fe(C5H5)(C18H15N2O)], a product of the reaction of 2-ferrocenylbenzoic acid and 2-amino-6-methylpyridine, crystallizes with two dissimilar molecules in the asymmetric unit. In one molecule, the picoline amide group is directed away from the 2-ferrocenylbenzene moiety (anti) whereas in the other, these are proximate (syn). In the crystal structure, molecules aggregate into dimers via cyclic, asymmetric N-H...N interactions with graph set R22(8), and are further augmented via intramolecular C-H...O=C and interdimer C-H...[pi](arene) interactions. Dimers are linked into chains along the  direction via weak C-H...O hydrogen bonds.
