Synthesis and characterization of group VIB metal carbonyl heteroacene complexes

Group VIB metal carbonyl heteroacene complexes were synthesized and characterized. Single crystal X-ray diffraction confirms that all metal carbonyl complexes bond to the ligand through the phenanthroline unit. Their absorption spectra are red-shifted compared to that of the ligand and their cyclic voltammetry revealed that their reduction occurred at less reducing potentials than the corresponding reduction in ligand.
