Synthesis and Spectral Studies of Metal Complexes Derived from Aromatic Heterocyclic Schiff bases

Abstract

Complexes of the type MLCl₂ [M═Co(II), Ni(II) and Cu(II)] where L ═ Schiff base derived from condensation of salicylaldehyde/substituted salicylaldehyde with ethyl-3-amino-2-benzofurancarboxylate were synthesised. All the complexes were characterised by the elemental analysis, IR, electronic and magnetic susceptibility data. The conductance measurements in DMF indicate the nonelectrolytic/electrolytic nature of the complexes. The IR spectral data suggest that all the ligands act as neutral bidentates towards all the complexes. Based on the IR, electronic and magnetic data polymeric octahedral structures are proposed for all the complexes.
