A new oxidovanadium(IV) Schiff base complex containing asymmetric tetradentate ONNO Schiff base ligand: synthesis, characterization, crystal structure determination, thermal study and catalytic activity
Original language description
After synthesis of an asymmetric tetradentate ONN0O0 Schiff base ligand (H2L) followed by reaction of the synthesized H2L with an equimolar mixture of methanolic solutions of the VO(acac)2, a new oxidovanadium(IV) Schiff base complex (VOL) was synthesized. The Schiff base ligand and its complex were characterized by FT-IR and UV?vis spectra and C, H, N analysis. The crystal structure of VOL was also determined by single crystal X-ray analysis. The VOL complex crystallizes in monoclinic space group Cc. The Schiff base ligand acts as a tetradentate ligand through its two iminic nitrogens and two phenolic and acetylacetonate oxygens. Thermogravimetric analysis of the VOL showed that it decomposes in two steps and converts to mixed vanadium oxides at 477 8C. In addition, thermal decomposition of the VOL complex in air at 660 8C leads to formation of V5O5 nanoparticles with the average size estimated from XRD 49 nm.
