Synthesis, characterization and molar conductivity of 1,1-cyclobutanedicarboxylate platinum (II)‎ and palladium (II)‎ complexes with histidine and tryptophane

Abstract EN

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] .
