| The new complexes CuX(2)(LH(2)), CuX(2) (SH3) (X = Cl, Br), CuX(LH(2)), CuX(SH3) (X = Cl, Br, l), CuX(H(4)MTO)2 (X = Cl, Br), CUI(H(4)MTO) and CuX(H(3)MMTO)2 (X = Cl, Br, l), where LH(2) = N,N'-dimethylmonothiooxamide, SH3 = N-(s)-methylmonothiooxamide, H(4)MTO = monothiooxamide and H(3)MMTO = N-(o)-methylmonothiooxamide, have been prepared. The complexes were characterized by elemental analyses, conductivity measurements,magnetic moments and spectroscopic (UV/VIS, FT-IR, Laser-Raman) studies. The vibrational analysis of the complexes has been given using NH/ND, CH3/CD3 and (CU)-C-63/(CU)-C-65 isotopic substitutions. The neutral monothiooxamides behave as monodentate ligands in the Cu(l) complexes coordinating through their thioamide sulfur atom. The ligands LH(2) and SH3 act as bidentate chelating agents in the Cu(ll) complexes with ligated atoms being the thioamide sulfur and the amide oxygen. | | |
