Synthesis and Spectroscopic Study of Palladium Pd (II) Complexes from Mixed Ligands

Palladium (II) (Pd) complexes were synthesized from[(1-Naphthyl) ethylenediamine dihydrochloride](C_12 H_14 N_2.2HCl) asprimary ligand, and malonic acid, oxalic acid and sodium pyrophosphateas secondary ligands with (1:1) mole ratio [Pd(C_12 H_14 N_2)Cl_2], [Pd(C_12 H_14 N_2)(ox)],[Pd(C_12 H_14 N_2)(ma)] and [Pd(C_12 H_14 N_2))(pyph]. The complexes were identified by mass spectroscopy ,elemental microanalysis, Chloride Contents ,molar conductivity and melting point. The complex products had square plane geometry quantitatively measured at 410 nm at optimal reaction. Results suggested that [1-Naphthyl) ethylenediamine dihydrochloride] oxalic and malonic acids and sodium pyrophosphate behave as bidentate ligands with Pd (II) ion. Geometrical structure was based on data from previous techniques. We find that [ (1-Naphthyl) ethylenediamine dihydrochloride] detector can beused in spectral analysis to estimate micrograms of palladium ions as it complexes with colored solutions or sediments resulting in super absorbent peaks within calibration curves for each ion.
