Synthesis and characterization of new Co(II)‎, Ni(II)‎ and Cu(II)‎ complexes and adducts with tetramethyl thiuram monosulfide

الملخص EN

The present investigation involves the synthesis of some new Co(II), Ni(II) and Cu(II) complexes with tetramethyl thiuram monosulfide and their adducts with monodentate donor ligands (triphenyl posphine) gave 1:2 adducts, while with bidentate donor ligand (1,10-phenanthroline) form 1:1 adducts.

The complexes and adducts were characterized by their elemental analysis, IR and UV-Vis spectroscopy, conductivity and magnetic measurements.

Conductivity data in DMSO showed that some of the complexes and adducts are non-conductive assigning the formula [MLCl2] or [M(L)2Cl2] and some of them are 1:2 conductive assigning the formula [M(L)(L`)]Cl2.Explanations for the structural elucidation of these complexes which have tetrahedral geometry and the adducts which are a signal as octahedral enviroment.
