Abstract
The structure and bonding of several substituted benzenes (C6H5F, 1,4C6H4F2 and 1,3,5-(C6H3(CH3)3) with vanadium has been investigated by electron paramagnetic resonance (EPR) spectroscopy and semi-empirical quantum chemical ZINDO/1 calculations. As the arene electron withdrawing ability increases, the vanadium hyperfine splitting of the corresponding organometallic complex decreases. The calculated vanadium-ligand bond dissociation energies for these complexes increases with the increase of the π-electron density in their 2pz(C) orbitals. These observations indicate that EPR may be a rapid probe for the analysis of vanadium organometallic compounds.
