Abstract: | The diethyldithiocarbamate chelates of copper (II), lead (II) and tin (IV) have been prepared and characterized. Pure or nearly pure metal diethyldithiocarbamate (DEDTC) chelates could be prepared through recrystallization. The x-ray photoelectron spectra (XPS) for the recrystallized samples were obtained. Three different carbons (C Is) in the diethyldithiocarbamate molecule can be recognized through a computer deconvolution system. Sulfer 2p showed two peaks of spin doublet S 2p1/2 and S 2p3/2. Based on the XPS results we may conclude that the diethyldithiocarbamate ligand forms an unusual 4-membered chelate ring structure with the metal ion, both sulfur having bonding with the metal. The N in the DEDTC may also bind with the metal. |
