Hindawi - Mixed Ligand Complexes of N-Methyl-N …
Abstract A series of mixed ligand dithiocarbamate complexes with a general formula [ML 2 (py) 2], where M = Mn(II), Co(II), Ni(II), and Cu(II), py = pyridine, and L = N-methyl-N-phenyl dithiocarbamate have been prepared and characterised by elemental analysis, FTIR and Uv spectroscopy, magnetic moment, and thermogravimetric and conductance analysis.
This observation shows that the interaction between the amine group of FGCX and the metal ions is ionic in nature and raising the ionic strength reduces their movement to the solid surface . Among the five metals investigated Pb and Cu proved to have higher binding strength even when the concentration of Na + was increased.
Ion - Wikipedia
The resulting compound is called an ionic compound, and is said to be held together by ionic bonding. In ionic compounds there arise characteristic distances between ion neighbours from which the spatial extension and the ionic radius of individual ions may be derived.
