Novel tricarbonyl-molybdenum complexes bearing monoaza-trithia-macrocyclic ligands (LX^R), [Mo(CO)₃(LX^R)] (X = 12 or 14, R = H), and [Mo(CO)₃(L14^Py)Mo(CO)₄] have been synthesized to gain an understanding of the unique properties of macrocyclic ligands. X-ray structure analysis of [Mo(CO)₃(L14^H)] has revealed that intra- and intermolecular hydrogen bonds existed and these interaction regulated CO bond lengths. In addition, vibrational spectroscopy indicates that a specific hydrogen bonding interaction affects the strength of the binding of carbon monoxide molecules to the metal. In case of using L14 ^Py, it is expected that dinuclear molybdenum complex was generated.
