Electronic and electron paramagnetic resonance spectra and metal–ligand bonding of VF4

Abstract

The electronic and EPR spectra of the tetragonally compressed VF₆^2– complex present in VF₄ have been recorded. Transitions to the levels derived from the ²E_g state of the parent octahedral complex occur in the visible region, while those between components of the ²T_2g ground state occur in the infrared region. Angular-overlap and molecular-orbital X_α calculations are presented and compared with previous results for other complexes.
