ABSTRACT
The metal complexes of ligands Adenine, Adenine-Cytosine, Barbituric acid, Thiobarbituric acid and 2-Thiouracil were synthesized. The infrared spectral measurements assigned the characteristic bands and mode of bonding. The electronic absorption spectra and magnetic properties of the complexes revealed the tetrahedral, square pyramidal and octahedral geometries. The Mössbauer spectra for Fe(Adenine)3 complex proved a high spin FeIII complex .
