Synthesis and Characterization of Some Zinc(II) and Cadmium(II) Complexes with Schiff Bases


A number of zinc(II) and cadmium(II) complexes with two Schiff base ligands have been prepared. The ligands derived from the condensation of furfuraldehyde with butylamine (FBA) and hexylamine (FHA). The complexes which have the molar ratio of 1:2 (metal to ligand) had general formula [M(L)2]X2 (where M = Zn(II) or Cd(II) ; while X = Cl, NO3 or ½ SO ). The complexes were characterised by molar conductance measurements and the study of their infrared and ultraviolet absorption spectra, while zinc and cadmium contents were determined by standard procedures. These studies revealed the action of both ligands as neutral bidentate chelating ligands, formed complexes with tetrahedral structure
