Synthesis, Structure and Application of Mixed-Ligand Coordination Compounds of Copper(II) with Substituted Thioamides

Abstract

New coordination compounds of copper(II) with substituted thioamides of the general formula [Cu(HL6-9)2X2]2 and CuL2 6-9 have been synthesized. The consecutive reaction of nucleophilic substitution/elimination of SN 1/E1 in the octahedral complex [Cu(NH3)4Cl2]·H2O and catalytic hydrolysis of [Cu(HL6-9)2X2]2 complexes have been investigated. Using IR spectroscopy, elemental and XRD analysis, the composition and structure of the synthesized complexes have been determined. The molecular and crystalline structure of the complex [Cu(C30H26Cl2N6O8S2)]·i-C3H7ON was determined by X-ray diffraction analysis. The tribotechnical characteristics of some coordination compounds as additives to industrial oils have been investigated.
