Electrochemical synthesis, structure, magnetic and tribochemical properties of metallochelates of new azomethine ligands, bis-[2-(N-tosylaminobenzylidenealkyl(aryl)]disulfides
摘要:
On the basis of new ligand systems, bis-azomethines of N-tosylaminobenzaldehyde and alkyl(aryl)diaminodisulfides, mono- and binuclear chelates with 4N- and 2N2S-ligand arrangement were chemically (from metal acetates) or electrochemically (from metals in the zero oxidation state) first synthesized and characterized. Mononuclear chelates have a tetrahedral structure. In binuclear copper complexes the magnetic exchange interaction of the antiferromagnetic type was observed. Bisazomethines of disulfides were used as additives to lubricant oils.
Electrochemical synthesis and crystal structure of iron(II), cobalt(II), nickel(II) and copper(II) complexes of dianionic tetradentate N4 Schiff base ligand
Abstract The electrochemical oxidation of anodic metal (iron, cobalt, nickel and copper) in an acetonitrile solution of the potentially chelating Schiff base N,N(dithiodiethylenebis-(aminylydenemethylydene)-bis(1,2-phenylene)ditosylamide (H2L) afforded stable complexes of empirical formula [ML]. The compounds obtained have been characterized by microanalysis, IR spectroscopy and ES-MS mass spectrometry
