Özet:

 

Multidentate N-ligands (Schiff bases) were prepared by the  condensation of 2-acetylpyridine or 2-benzoylpyridine, and  1,2-diaminoethane or 1,6-diaminohexane (2:1 ratio) in ethanol.  These  ligands were reacted with Mo(CO)6 to obtain dinuclear metal  tetracarbonyl compounds.  Both terminal amine groups were seen to form  imines from the reaction of mono-ketones with diamines in 2:1 or 1:1  ratios.  The structures of these ligands and metal complexes were  characterized by elemental analysis, and FT-IR, 1H-NMR, 13C-NMR,  and LC-MS spectral techniques. N,N'-bis[1-(pyridin-2-yl)ethylidene]ethane-1,  2-diamine, which was obtained by the reaction of 2-acetylpyridine and  1,2-diaminoethane, was also characterized by single crystal X-ray  structure analysis.  The crystal packing is stabilized by  intermolecular H-bonding and p-p interactions.
