Abstract The reactions of [Mo(CO) 6 ] towards a 2,6-di(imino)pyridine L 1 and related ligands were studied. The reaction with L 1 afforded two new complexes, [Mo(CO) 4 L 1 ] ( 1 ) and [Mo(CO) 4 L 2 ] ( 2 ), where L 2 is the 2-amino-6-iminopyridine ligand arising from the hydrogenation of one imine function of L 1 ; similar reaction with a 2-acetyl-6-iminopyridine ligand L 3 afforded [Mo(CO) 4 L 3 ] ( 3 ). Compounds 1 , 2 and 3 have been fully characterised by IR, 1 H NMR and X-ray crystallography; they present a metal ion in a pseudo-octahedral environment, the three organic ligands acting with bidentate N 2 coordination modes. One of the imine functions in 1 , the amine function in 2 , and the ketone function in 3 are uncoordinated.
