Synthesis and Characterization of New Co(II), Ni(II) and Cu(II) Complexes and Adducts with Tetramethyl thiuram monosulfide
الملخص
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.
