Synthesis and characterisation of vanadium(III) complexes of biphenylphenols
The vanadium(III) complexes of composition [VCl(3-n) (OAr(1,2))(n center dot)(THF)(2)] (OAr(1) = 2-phenylphenoxo and OAr(2) = 4-phenylphenoxo, THF = tetrahydrofuran; n = 1 -> 3) were prepared by in situ reaction of VCl(3 center dot)(THF)(3) with sodium salt of respective phenols in tetrahydrofuran. The complexes were characterised by elemental analysis, molar conductance, FTIR, UV-Vis, and FAB-mass spectral and magnetic studies. The thermal behaviour of some of the complexes was studied by TG-DTA. The dinuclear phenoxy bridged octahedral structures for the complexes were inferred from the spectral and magnetic studies.
