Two copper(II) coordination complexes based on sulfanilamide ligand: Synthesis, structure, thermal analyzes, electrochemical properties and biological activities

Synthesis, Structural Characterisation, and Electrochemical Properties of Copper(II) Complexes with Functionalized Thiosemicarbazones Derived from 5-Acetylbarbituric Acid

“…In this study, we synthesized eight new copper(II) complexes (1-8) with the ligands 5-acetylbarbituric-4-diethylthiosemicarbazone (H 2 AcbDM) and 5-acetylbarbituric-4Nhexamethyleneiminyl thiosemicarbazone (H 2 Acbhexim). The complexes were characterized by spectroscopy, and the crystal structures of three of them, [Cu(HAcbDM) (4), and [Cu(HAcbHexim)Cl] (6), were determined by single-crystal X-ray diffraction. All complexes are monomers and not electrolytes, except [Cu(HAcbDM)(H 2 O) 2 ]ClO 4 , which is a 1:1 electrolyte, and the nitrate derivative with H 2 AcbDM, which is possibly a mixture of [Cu(HAcbDM)…”

“…Because of their utilitarian properties and interesting structures, coordination compounds have attracted increasing interest. The rapid development of materials science and crystal engineering has greatly encouraged the use of complexes as functional materials, such as photocatalysts, supercapacitors, nonlinear optical materials, porous materials, and biomedical applications [4]. From this perspective and from the point of view of sustainability, the metal complexes used in these applications must be manufactured from sufficiently abundant materials and, in order to enter mass market applications, costeffective metals with a d 10 orbital configuration-such as Cu(I)-have to be, and currently are, the center of numerous research studies.…”
