Abstract :The vanadiuminsert ignore into journalissuearticles values(III); complexes of composition [VCl3-ninsert ignore into journalissuearticles values(OAr1,2);n.insert ignore into journalissuearticles values(THF);2] insert ignore into journalissuearticles values(OAr1 = 2-phenylphenoxo and OAr2 = 4-phenylphenoxo, THF = tetrahydrofuran; n = 1 /to 3); were prepared by in situ reaction of VCl3.insert ignore into journalissuearticles values(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.
