Abstract: 
Coordination compounds of general formula CuL have been obtained via complexation of copper(II) acetates and chlorides, as well as precipitated Cu(OH)2 with benzimidazole-2-N-arylcarbothioamides (HLI-IV). Monocrystal of [Cu(C16H14N3S)2]i-C3H7OH complex has been obtained by slow evaporation of CuL chelate saturated solution in isopropyl alcohol. The obtained compounds were investigated by means of elemental, XRD analysis and IR-spectroscopy. The investigated crystal structure is a solvate of copper(II) crystal complex of [Cu(C16H14N3S)2] composition and isopropyl alcohol with the ratio of 1:1. The central atom of copper(II) is coordinated by two atoms of nitrogen and sulfur of deprotonated thioamide ligand. Antiwear and antifriction properties of lubricating compositions based on I-20A industrial oil and synthesized CuL complexes have been examined.
