Chemical and spectroscopic studies of a new palladium(II) complex with N-acetyl-L-cysteine

Chemical and spectroscopic studies of a new palladium(II) N-acetyl-L-cysteine complex are described. Elemental analyses for the solid complex are consistent with the formula [Pd(C5H8NO3S)(2)] H2O or [Pd(NAC)(2)] H2O. Solid-state C-13 nuclear magnetic resonance (NMR), UV-Visible (UV-Vis) and infrared (IR) spectroscopic analyses are consistent with coordination of the ligand to palladium(II) through the nitrogen and sulfur atoms in a square-planar geometry. Thermogravimetric and differential thermal analyses confirmed the composition; final residue was identified as metallic palladium.
