Oxovanadium(IV) and oxovanadium(V) complexes of tropolone (Htrp, 2-hydroxi-2,4,6-cycloheptatrien-1-one), of stoichiometry VO(trp)2 and VO(trp)2Cl, were characterized by electronic, infrared and Raman spectroscopy. Their electrochemical behavior was investigated by cyclic voltamperommetry in dimethylsulfoxide solutions. The magnetic susceptibility of VO(trp)2 was investigated in the temperature range between 2 and 300 K. The vibrational spectra of the related Co(trp)2, Cu(trp)2 and Zn(trp)2 complexes were also analyzed for comparative purposes.
