Abstract

Four oxovandium(IV) complexes with carboxylate ligands, $VO(picn)_2$, $VO(htmq)_2$, $VO(quin)_2$ and $VO(pyra)_2{\cdot}2H_2O)$ have been prepared and studied. Infrared spectral data coupled with the results of magnetic susceptibility study strongly suggest that there are relatively strong intermolecular interactions in $VO(picn)_2$ and $VO(htmq)_2$. In all oxovanadium(IV) complexes studied in this work, the carboxylate ligand coordinates to the metal ion in the unidentated fashion. Some fundamental vibration modes of oxovanadium(IV) complexes were empirically assigned from the difference in the spectrum of metal complex with free ligand.
