Platinum(II)–dithiocarbamate complexes with phosphines: Synthesis, characterization and precursor for Pt nanoparticles using ultrasound assisted method

The reaction between Na2[PtCl4] and thymine bisdithiocarbamate (tdtc) in a 2:1 molar ratio (Metal:Ligand) produced a square planar complex called [Pt(tdtc)2]n (1). By reacting [Pt(tdtc)2]n with different phosphine ligands, such as Ph2PCH2PPh2 (dppm), Ph2PCH2CH2CH2PPh2 (dppp), and PPh3, the complexes...

Description
Summary:The reaction between Na2[PtCl4] and thymine bisdithiocarbamate (tdtc) in a 2:1 molar ratio (Metal:Ligand) produced a square planar complex called [Pt(tdtc)2]n (1). By reacting [Pt(tdtc)2]n with different phosphine ligands, such as Ph2PCH2PPh2 (dppm), Ph2PCH2CH2CH2PPh2 (dppp), and PPh3, the complexes [Pt(dtc)2(dppm)2]n, [Pt(dtc)2(dppp)]n and [Pt(tdtc)2(PPh3)2]n were obtained. Various characterization techniques, including FTIR, molar conductivity,1H-NMR, and 31P-NMR, were used to analyze these complexes. The results demonstrated that the tdtc ligand acts as a monodentate ligand, binding to the metal center through the soft sulfur atom in the presence of phosphines and bidentate chelating in the absence of phosphines. Furthermore, the complex [Pt(dtc)2(dppp)]n was transformed into platinum nanoparticles (Pt NPs) through the application of ultrasound. The resulting platinum nanoparticles were characterized using UV-Vis, TEM, and XRD.
