A second-row transition metal complex {MoTp(NO)(DMAP)} (DMAP = 4-(dimethylamino)pyridine; Tp = tris(pyrazolyl)borate) is shown to form dihapto-coordinate complexes with a range of substituted pyridines bearing both electron-withdrawing and electron-donating substituents. Subsequent reactivity of the pyridine ligand is demonstrated by protonation and nucleophilic addition reactions.
