X-ray Crystallographic Studies of Dioxouranium(VI), Dioxomolybdenum(VI) and Oxovanadium(II)Complexes of o-Hydroxy Acetophenone Oxime

Abstract

The ketone o-hydroxyacetophenone was treated with hydroxylamine hydrochloride for the synthesis of its oxime derivative. The oxime was used to synthesize dioxouranium(VI), dioxomolybdenum(VI) and oxovanadium(II) complexes. Elemental analysis, molar conductivity measurements, magnetic susceptibility measrements, ESR, electronic absorption and IR absorption spectra characterized the ligand and the metal complexes. The elemental analysis reveals the metal : ligand stoichoimetry in the complexes
as 1 : 2. Dioxouranium and dioxomolybdenum complexes were
found to be diamagnetic, whereas oxovanadium complex was found
to be paramagnetic in nature. The XRD data was to index the
complexes for monoclinic system with space group P_2/m. B_2/m and
C_2/c.
