Synthesis and characterization of group VIB metal carbonyl heteroacene complexes

• Group VIB metal carbonyl complexes contain a heteroacene ligand.
• UV–vis spectra of the complexes are red-shift compared to that of the ligand.
• X-ray crystal structures of all the carbonyl complexes were obtained.

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.

This article describes the synthesis and characterization of group VIB metal carbonyl heteroacene complexes. Metal carbonyl complexes bond to the ligand through the phenanthroline unit and their structures are confirmed by single-crystal X-ray diffraction analysis.Figure optionsDownload as PowerPoint slide
