This research includes synthesis and characterization of some Homogeneous and Heterogeneous binuclear complexes of Pd(II),Hg(II) with mixed ligands of dithiocarbamate derived from Uracil and tertiary phosphines . The formed complexes have the general formula of [M2 (U-DTC)2 (Phosphine)n] Uracil bis(dithiocarbamate) = (-DTC) M = Pd(II),Hg(II) n=2 or 4 mole. The synthesized complexes were identified using the micro elemental analysis (C.H.N.S), electrical molar conductivity, spectra methods (IR and1H, 31P-NMR). Antibacterial activity of ligands and complexes was evaluated with two types of bacteria Staphylococcus aureus (gram positive) and Escherichia coli (gram negative). According to the results obtained from the physical and spectral measurements, palladium (II) complexes have a square planer shape, and mercury (II) complexes have a tetrahedral arrangement.
Key words: Dithiocarbamate, tertiary Phosphine, Uracil bis(dithiocarbamate)
