Synthesis, characterization and magnetic properties of binuclear oxovanadium(IV) complexes with a bromanilate bridge

Article abstract of DOI:10.1080/00945719909349506

Four novel oxovanadium(IV) binuclear complexes have been synthesized and identified [(VO)₂(BA)L₂]SO₄ [L denotes 2,2'-bipyridine (bpy); 1, 10-phenanthroline (phen); 2,9-dimethyl-1, 10-phenanthroline (Me₂-phen) and 5-chloro-1, 10-phenanthroline (Cl-phen), respectively], where BA represents the dianion of bromanilic acid. The complexes were characterized by elemental analyses, molar conductivity and room temperature magnetic moment measurements, IR and electronic spectral studies. Based on these studies, extended BA-bridged structures consisting of two vanadium(IV) ions, each in a square-pyramidal environment, are proposed for these complexes. The complexes [(VO)₂(BA)(bpy)₂]SO₄ (1) and [(VO)₂(BA)(phen)₂]SO₄ (2) were characterized by variable temperature present complexes than that of the complexes [(VO)₂(CA)L₂]SO₄ (L = bpy and phen), so as to increase the antiferromagnetic interaction. This would explain the difference in J values for these complexes.
