Characterization and Comparison of the Reaction Product of (Pd, Pt, Ag and Au) in Different Solvent with Diaminothiuramdisulfide

Abstract

The work presented in research describes the preparation and characterization of new complexes resulted from the reaction of diaminothiuramdisulfide(tds)with metals (or metals chlorides)of group(VIII)[Na2pdcl4,Pt(0) and K2ptcl4]in addition to group(IB)metals[Ag(0) ,AgCl and Au(o)]. The thiuramdisulfide compound (tds) reduced to the corresponding aminodithiocarbamate anion (H2NNHCS2)-in some complexes(Oxidative addition reaction ) However, in the remaining complexes the (tds)were simply added to the metal chloride ( addition reaction) without cleavage of the –S-S-bond.the resulting complexes can be classified as follows. I-The oxidative addition reactions offered complexes of the type:1-[M(L)2]((Where L=H2NNHCS2-(aminodithiocarbamate anion) and M=Pd(II),Pt(II) , Ag(II ))and [Ag2(L)4NiCl2].2-[M(L)3][M=Au(III)]in addition to the complexes[Au(L)3(1,10 –Phen)] .II-The addition reactions resulted in the formation of the complexes [M(tds)Cl2] whene Pt(II).The prepared complexes were characterized using molar conductivity, UV-Vis and IR spectra in addition to magnetic measurements and metal analysis by atomic absorption .The results suggest a tetra-or hexa-coordinated complexes and also displayed the importance of using different solvents upon the type of reaction and prodect.
