SYNTHESIS, SPECTROSCOPIC STUDY AND BIOLOGICAL ACTIVITY FOR PD (II) COMPLEXES FROM MIXED LIGANDS

Abstract

Pd(II) complexes were synthesized from 2-(4-antipyrine azo)-4-nitroaniline (C17H16O3N6) as primary ligand, and (Oxalic acid, Malonic acid, sodium pyrophosphate) as secondary ligands using metal: ligand in (1:1) mole ratio with molecular formula [Pd(C17H16O3N6)Cl2], [Pd(C17H16O3N6)(ox)], [Pd (C17H16O3N6)(ma)],[ Pd (C17H16O3N6) pyph]. These complexes were characterized byspectral methods FTI.R, (U.V–Vis), (A.A), mass spectroscopy, (C.H.N), Magnetic moment, molar conductivity and melting point measurements. The complexes product gave square planer geometry. A fast, simple, sensitive and validated spectrophotometric approachwas described for determining palladium(II)with the use of 2-(4-antipyrine azo)-4-nitroaniline. The complex product has been quantified at 595 nm length and the best conditions for interaction have beeninvestigated and improved.Biological activity of the complexes were tested on three types of fungus Aspergillus niger, Aspergillus parasiticus, Penicillium sp., which showed high toxicity by measuring the diameters of the fungus used.
