Studies on the binary complexes of Ni [II], Cu [II] and Pt [IV] with oxazolidine and imidazolidine derivatives

Some oxazolidine and imidazolidine derivatives were synthesized to investigate their complexing behavior with Cu [II], Ni [II] and Pt [IV] ions. Ni [II], Cu [II] and Pt [IV] complexes with 5-imino-3- [p-fluorophenyl]-2-methyloxazolidine-4-thione [Pfox] and with 5-imino- 1-phenyl-3[p-fluorophenyl]-2-imidazolidine-4-thione [pfim] were characterized by elemental analysis, TGA, IR, electronic absorption spectra, molar conductance, and X-ray diffraction studies. Complexation equilibria and the stabilities of these binary complexes obtained in solution were studied potentiometrically and spectrophotometrically in a 1:1 molar ratio in 40% ethanol-water mixture at the constant ionic strength [I = 0.1 M NaClO4]
