Abstract

A novel mononuclear Cr(III) coordination compound, [Cr(HL)(N₃)₂], was synthesized by the reaction of CrCl₃·6H₂O and NaN₃ with the Schiff base ligand (H₃L-Cl). The synthesized ligand and [Cr(HL)(N₃)₂] were characterized by spectroscopic methods. Single-crystal X-ray analysis was also accomplished to confirm the structure of the synthesized Cr(III) compound. According to the results of X-ray analysis, this compound crystallizes in the triclinic system with P-1 space group and the CrN₆ coordination environment around the Cr(III) ion can be described as a distorted octahedral geometry. The catalytic activity of [Cr(HL)(N₃)₂] was investigated in the oxidation of benzyl alcohol in presence of hydrogen peroxide. The effects of various parameters were investigated, such as the amount of catalyst, the concentration of oxidant, temperature and solvent. The results show that [Cr(HL)(N₃)₂] has high activity and stability in the investigated oxidation reaction and could selectively convert benzyl alcohol into benzaldehyde. The electrochemical behaviors of the ligand and [Cr(HL)(N₃)₂] were also investigated by cyclic voltammetry.

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
