Synthesis Structural and Spectroscopic Study for Pd (II) complexes with 4-aminoantipyrine and Sodium pyrophosphate.

Abstract

Pd (II) complexes were synthesized from 4-Aminoantipyrine (4-AAP) as primary ligand, and disodium pyrophosphato as secondary ligands using metal: ligand in (1:1) mole ratio with molecular formula [Pd(4-AAP)Cl2],[Pd(4-AAP) (Pyph)]. These complexes were characterized by elemental microanalysis (C.H.N), (A.A), [I.R, (U.V–Vis), mass spectroscopy], along with molar conductivity, Chloride contents and melting point measurements. The ligands (4-AAP) and (Pyph) gave square planar geometrical formula with Pd (II). Rapid, simple, sensitive and validated spectrophotometric method has been described for the determination of palladium (II) using 4-aminoantipyrine. The complex product was quantitatively measured at 363nm and the reaction conditions were studied and optimized.
