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.
