Synthesis and characterization of Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II), dioxouranium(VI) and Th(IV) complexes with a schiff base

Abstract

Complexes of the type MLCl₂[M= Co(II), Ni(II), Cu(II) and Cd(II)] and Ml₂CI₂[M = Zn(II), Hg(II), dioxouranium (VI) and Th(IV)] and L= schiff base derived from 4-hydrazinobenzofuro[3,2-<i>d</i>]pyrimidine and 4-hydroxy-3-aldehydodiphenyl have been reported and characterized on the basis of analytical, magnetic momellt, conductance, electronic and infrared spectral data, The ligand field parameters have been evaluated for Co(II), Ni(II) and Cu(II) complexes which suggest an octahedral geometry for each of them, The infrared spectral data reveal the bidentate nature of the ligand.
