| Abstract | ||
| Four complexes of the type [M(AA)(CBDCA)] (where M = pt , pd ; AA= histidine (His) , tryptophan (Trp) amino acids which contain heterocyclic ring ; CBDCA=1,1-cyclo-butandiicarboxylate) have been prepared . The structural information of these complexes characterized by infrared, U.V-visible spectroscopy and molar conductivity measurements. Both the histidine and trptophan ligands are bond with platinum(II) and palladium(II) in a bidentate fashion through the amino nitrogen and oxygen atom of carboxylate group. The electronic transitions appeared as d-d transitions and U.V-visible together with I.R spectra of these complexes have been given square planner geometry and C2V point group. All the prepared complexes have shown a weak electrolyte in DMF solvent. The stability of complexes arrange according to the increase of the stability as follows: [I] > [II] > [III]>[IV] . | ||
