摘要:

The new complexes trans-[PdX2(H4MTO)2] (X = Cl, Br, I),trans-[PdX2(H3MMTO)2] (X = Cl, Br, I),trans-[PdX2(SH3)2] (X = Cl, Br), [Pd(H4MTO)4]CI2and [Pd(H3MMTO)4]CI2, where H4MTO = monothiooxamide, H3MMTO = N(o)-methylmonothiooxamide and SH3= N(s)-methylmonothiooxamide, have been prepared. The complexes were characterized by elemental analyses, conductivity measurements, X-ray powder patterns, thermal methods and spectroscopic (UV/VIS, FT-IR, Laser-Raman) studies. The vibrational analysis of the complexes is given using NH/ND and CH3/CD3isotopic substitutions. Monomeric square planar structures are assigned for the complexes in the solid state. The neutral monothiooxamides behave as monodentate ligands coordinating through their thioamide sulfur atom. The complex [Pd(SH2)2] was isolated during the thermal decomposition oftrans-[PdCl2(SH3)2].
