A novel chromium(III) coordination compound, [Cr(HL)2]Cl·3.3(CH3OH) (1) was obtained by the reaction of H2L = (E)-4-amino-N'-(5‑bromo-2-hydroxybenzylidene)benzohydrazide with CrCl3·6H2O in methanol. The structure of the obtained compound was characterized by UV–Vis, FT-IR and TGA analyses and determined by single crystal X-ray analysis. Results showed that [Cr(HL)2]Cl·3.3(CH3OH) is crystallized in the orthorhombic system (Ibca space group) and two molecules of H2L are coordinated to the chromium ion as ONO-donor ligand and formed distorted octahedral geometry. The catalytic oxidation of benzyl alcohol was performed in the presence of H2O2 for investigating the catalytic activity of [Cr(HL)2]Cl·3.3(CH3OH). To obtain optimal condition, the effect of some parameters (concentration of oxidant, amount of catalyst, solvent and temperature) was investigated. The results confirm that chromium(III) coordination compound has high activity and selectivity in converting benzyl alcohol into benzaldehyde.
