Synthesis, Structure and Properties of Copper(II) Chelates with Benzimidazole-2-N-Arylcarbothioamides

Abstract

Комплексоутворенням ацетатів і хлоридів купруму(ІІ), а також свіжоосадженого Cu(OH)2 з бензіміда-золіл-2-N-арилкарботіоамідами (HLI–IV) отримано коорди-наційні сполуки загальної формули CuLI IV2- . Монокристал комплексу [Cu(C16H14N3S)2]×і-С3Н7ОН отримано повільним випаровуванням насиченого розчину хелату CuL II 2 в ізопропіловому спирті. Отримані сполуки досліджено методами елементного, рентгеноструктурного аналізу та ІЧ-спектро- скопією. Досліджена кристалічна структура монокристалу є сольватом комплексу купруму(ІІ) складу [Cu(C16H14N3S)2] та ізопропілового спирту в співвідношенні 1:1. Центральний атом купруму(ІІ) координований двома атомами нітрогену та сульфуру депротонованого тіоамідного ліганду. Досліджено протизношувальні та антифрикційні властивості мастильних композицій на основі індустріальної оливи І-20А тасинтезованих комплексів CuL I IV2- . Coordination compounds of general formula CuL I IV2- 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 II 2 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 CuLI IV2-complexes have been examined.
