Synthesis and characterisation of vanadium(III) complexes of biphenylphenols

The vanadium(III) complexes of composition [VCl3-n(OAr1,2)n.(THF)2] (OAr1 = 2-phenylphenoxo and OAr2 = 4-phenylphenoxo, THF = tetrahydrofuran; n = 1 /to 3) were prepared by in situ reaction of VCl3.(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.
