Abstract

In this work, new coordination compounds of copper (II) with N-acetylthiourea (NAT) in various media (ethanol, HCl) were synthesized. The complexes of the following compositions were obtained: [CuNAТ(H₂O)₂]Cl₂, [Cu(NAT)₂SO₄]∙2H₂O, [Cu(NAT)₂Br₂]∙H₂O, [CuNAT(NO₃)₂]∙2H₂O, [CuNAT(ClO₄)₂]∙3H₂O. Their physical and chemical properties were studied using elemental analysis, IR spectroscopy, potentiometry and conductometry. It was found that N-acetylthiourea is coordinated to the central copper atom as a monodentate (via sulfur) or bidentate (via sulfur and oxygen) ligand, which is accompanied by the formation of chelate structures. IR spectroscopy data confirmed the shift of absorption bands characteristic of C=S and C=O, as well as the presence of coordinated and crystallization water. The obtained compounds demonstrate promising properties, allowing them to be considered as candidates for use in catalysis and biological systems.
