“…They are able to coordinate metals through imine nitrogen and another group, more often than not, linked to aldehyde or ketone [4]. Schiff base metal complexes also find diverse and fruitful applications in industry and daily life [5][6][7][8][9][10]. There exist myriad reports on the biological activities of Schiff base ligands and their metal complexes, including their use for enzyme modeling, and catalytic activity and their function as antimicrobial, antifungal and antitumor agents [11][12][13][14][15].…”

In this research, we prepared a new series of the Cu(II) (1) and Ni(II) (2) metal complexes of a tridentate Schiff base ligand, (E)-2-(5-bromo-2-hydroxybenzylideneamino) phenol (H 2 L). These complexes were characterized by elemental analysis, FT-IR, UV-Vis, and 1 H-NMR spectroscopy. The crystal structures of (1) and (2) were determined by X-ray diffraction studies. The single crystal X-ray diffraction analyses revealed that copper(II) cation is five-coordinated and the coordination polyhedron is a slightly distorted square pyramid. Nickel(II), on the other hand, is four-coordinated, and has a regular, square planar geometry. Further discussed were the electrochemical reduction of these complexes. We also analyzed the nature of the metal-ligand bond in the complexes through NBO and EDA analysis. Besides, vibrational sample magnetometer (VSM) revealed complex (1) was ferromagnetic.

“…As an expected result of this, Schiff base metal complexes found diverse and fruitful applications in industry and daily life [5][6][7][8][9][10][11][12][13][14][15][16][17]. Within these privileged class of compounds, the synthesis of aromatic Schiff bases from both aromatic aldehyde and aromatic amine precursors are the most challenging route for synthetic chemists because of resulting in higher yield and purity than aliphatic ones based on the strength of relative stability of imine bonds conferred by electron-rich aryl side groups on the nitrogen and carbon atoms.…”

A novel 4,4'-bipyridine linked dinuclear copper(II) complex, [Cu 2 L 2 (bipy)](NO 3 ) 2 ·bipy (L = 2-{[2-(2-hydroxyethylamino)ethylimino]methyl}-6-methylphenol; bipy = 4,4'-bipyridine), was prepared and characterized by elemental analyses, IR spectroscopy, and single-crystal X-ray diffraction. The Cu···Cu distance is 11.129(2) Å. The Cu II atom is coordinated by one phenolate O, one imine N, and one amine N atoms of a Schiff base ligand, and one N atom of the bridging 4,4'-bipyridine ligand, forming a square planar geometry. In the crystal structure of the complex, the dinuclear copper complex cations are linked by 4,4'-bipyridine molecules through intermolecular O-H···N hydrogen bonds, to form 1D chains running in the [2 0 -1] direction.
