Abstract: Complexes of Fe(II), Co(II), Ni(II), Pd(II), and Cu(II) with 4-(3,5-diphenyl-2-pyrazolin-1-yl)-benzenesulfonic acid have been prepared and characterized by conductivity and magnetic moments measurements, solubility, thermal analysis, IR, electronic, and EPR spectra. The data show that the ligand coordinates with metal ions Fe(II), Co(II), Ni(II), and Pd(II) in the bidentate form, with the Cu(II) ion in the unidentate form and the structure was proposed. The complexes are nonelectrolytes in dimethylformamide and methanol.
