Mixed Ligand Complexes of Co(II) and Ni(II) Containing Organic Acids and Amine Bases as Primary and Secondary Ligands

Abstract

The synthesis and characterization of mixed ligand complexes of Co(II) and Ni(II) have been described. Organic dibasic acid, malic acid plays role as primary ligand and Heterocyclic amine bases play role as secondary ligands in the complexes. Melting points, Elemental analysis, Magnetic susceptibility measurements, IR, UV and 1 H-NMR spectral analysis were used in determining their physico-chemical properties. The prepared complexes of Co(II) and Ni(II) were found to form octahedral structure.
