dc.description.abstract | The chemistry of the divalent vanadyl cation, (VO)2 + , finds applications in the crude oil industry as well as in the biological realm. The N2 S2 tetradentate ligand N,N'-bis(2-mercaptoethyl)-l@5-diazacyclooctane, H2-bme-daco, has been shown to complex the vanadyl moiety. The resulting complex, (bme-daco)VO, exhibits square-pyramidal geometry about the vanadium atom with the donor atoms of the ligand forming the basal plane and the 0-atom at the apex. The vanadium atom lies 0.66 A above the best N2S2 plane. The synthesis and characterization of (bme-daco)VO are discussed and the complex is compared to other square-pyramidal systems of bme-daco, including [Ga-C,12,. In light of the reactivity of the nickel(II) analogue of (bme-daco)VO, the reactivity of (bme-daco)VO was examined and compared to the former complex. It appears that the electron withdrawing capacity of the vanadyl oxygen deactivates the thiolate sulfurs towards electrophiles; however, some reactivity was seen with hydrogen peroxide and sulfur dioxide. | en |
