Synthesis and properties of Complexes of Copper(II), Nickel(II), Cobalt(II) and Uranyl Ions with 3-(p-Tolylsulphonamido)rhodanine

Abstract

amido)rhodanine (HL) have been prepared and characterized by chemical and thermal analyses, molar conductivity, magnetic susceptibility measurements, and infrared, electronic and EPR spectra. The visible and EPR spectra indicated that the Cu(II) complex has a tetragonal geometry. From EPR spectrum of the Cu(II) complex, various parameters were calculated. The crystal field parameters of Ni(II) complex were calculated and were found to agree fairly well with the values reported for known square pyramidal complexes. The infrared spectral studies showed a monobasic bidentate behaviour with the oxygen and nitrogen donor system. Thermal stabilities of the complexes are also re
