Three crystal structures of (N-substituted 7-azabenzonorbornadiene)Fe(CO)4 derivatives have been studied for substituents 7-MeSO2 (1), 7-p-ClC6H4 (2), and 7-p-MeC6H4 (3), respectively. In the solid state, an intramolecular interaction between the N-nucleophile and the nearby coordinated CO ligand is clearly seen. As the N?C=O contact distance becomes shorter, the O atom of Fe-C-O bends away from the N atom more, corresponding to a stronger interaction between the nucleophile and the coordinated CO.
