Spectroscopic, biological activity and scanning electron microscope studies of Pd (ii) with Tetrazole-thione and Phosphines complexes

Five mixed-ligand phenyl Palladium (II) complexes containing 5-henzylthion-lH-tetrazole (LH) and phosphines (1-5) were synthesized. These complexes are classified into one groups: [PdL2(dppm)], [PdL2(dppe)], [PdL2(dppp)], [PdL2(dpph)], [PdL2(dppf)], (1,5). The complexes were prepared with moderate to high yields and characterized by various techniques. The characterization data indicated that the L-ligand acts a monodentate ligand through the nitrogen atom in the tetrazole ring in complexes (1-5), adopting a square planar geometry around the Pd(II) center. The crystal structure of the complexes was examined using scanning electron microscopy (SEM), and the results revealed the presence of normal nanostructures.
