| Abstract: | The formation of chloro- and azidocomplexes of VO2+(IV) is investigated in acetonitrile (AN), propanediol-1,2-carbonate (PDC), trimethyl phosphate (TMP) by spectrophotometric, potentiometric and conductometric methods. The following coordination forms are indicated: [VOCl]+ inAN, PDC andDMSO), [VOCl2] (inAN, PDC andTMP), [VOCl3]? (inPDC andTMP[?]), [VOCl4]2? (inAN, PDC andTMP); [VON3]+ (inAN, PDC andDMSO), [VO(N3)2] (inAN, PDC, TMP andDMSO), [VO(N3)2+n]n? (inAN, PDC, TMP andDMSO). The results are interpreted by the donor numbers and sterical properties of the solvent molecules. |
