Spectral and Physical Studying of Dithiocarbamate Mixed Ligand Complexes
Abstract
A number of mixed ligand dithiocarbamate complexes with the general formula [ML2(py)2] have been prepared and characterized by elemental analysis, FTIR and UV spectroscopy, magnetic moment, thermogravimetric and conductance analysis, and M = Mn (II), Co (II), Ni (II), and Cu(II), py = pyridine, and L = N-methyl-N-phenyl dithiocarbamate. It was demonstrated by the infrared spectra that the pyridine molecule in the complexes experienced neutral monodentate coordination through the nitrogen atom, whereas the dithiocarbamate moiety experienced symmetrical bidentate coordination through the sulfur atoms. It was demonstrated by the results of the magnetic moment, elemental analysis, and electronic spectra that the complexes adopted an octahedral geometry.
