Synthesis and Characterization of Oxo-and Dihalovanadium(IV) Compounds with Tetradentate Schiff Base Ligands
This project focuses on the synthesis and characterization of a series of tetradentate Schiffbase oxo-and dihalovanadium(IV) compounds derived from salH (salicylaldehyde), dialH (2,6-diformyl-4-methylphenoD , and two diamines; l,2-diaminoethane and l,3-diaminopropane. These compounds exhibit interesting trends in spectroscopic behavior which demonstrate their unusual properties among known vanadium(IV) compounds. There remains much work to be done in complimentary electrochemical studies and spectroscopy alike before these compounds can be said to be fully characterized, but progress is being made. Since dihalovanadium(IV) complexes are usually much more reactive than oxovanadium(IV) complexes, it may be possible to use them as a tool for exploring the chemistry which occurs at the vanadium center itself. Dihalovanadium compounds may also be used as intermediates in the search for compounds which could serve as models of vanadium in a natural system.
