Abstract

Fe(dmbipy)Cl4dmbipyH, 1 (dmbipy is 4,4'-dimethyl-2,2'-bipyridine), was prepared from reaction of FeCl3 6H2O with 4,4'-dimethyl-2,2'-bipyridine in 0.1 molar aqueous HCl. Treatment of 1 with dimethyl sulfoxide in methanol produced Fe(dmbipy)Cl3(DMSO), 2 (DMSO is dimethyl sulfoxide). Both complexes were characterized by IR, UV-vis, and 1H-NMR spectroscopies and their structures were studied by single crystal diffraction. Compounds 1 and 2 are high-spin with spin multiplicity of six.
