“…In the past decades, the crystal materials of supramolecular complexes have attracted great interest due to their potential applications in several fields [6][7][8]. The structure design and synthesis of new manganese complexes are of general interest and beneficial to the research of magnetic materials [9,10].…”

“…The compound formed by the condensation of an aldehyde and amine is generally known as Schiff base, whereas the N 2 O 2 -donor chelated Schiff base (N,N 0 -disalicylideneethylenediamine, Salen) formed by the condensation of two identical aldehyde molecules and one diamine molecule is abbreviated as Salen. [1][2][3][4][5] Salen-based compounds have four coordination atoms (O, N, N, and O) in the center and can be coordinated with various metal ions to form M-Salen complexes. [6][7][8] The structure of N and O coordination with metal ions of Salen complexes, [9][10][11][12] which is close to the biological environment, [13][14][15][16] has attracted considerable attention in the field of molecular recognition.…”

A new asymmetric Salamo-based ligand H 2 L was synthesized using 3-tert-butyl-salicylaldehyde and 6-methoxy-2-[O-(1-ethyloxyamide)]-oxime-1-phenol. By adjusting the ratio of the ligand H 2 L and Cu (II), Co (II), and Ni (II) ions, mononuclear, dinuclear, and trinuclear transition metal (II) complexes, [Cu(L)], [{Co(L)} 2 ], and [{Ni(L)(CH 3 COO)(CH 3 CH 2 OH)} 2 Ni] with the ligand H 2 L possessing completely different coordination modes were obtained, respectively. The optical spectra of ligand H 2 L and its Cu (II), Co (II) and Ni (II) complexes were investigated. The Cu (II) complex is a mononuclear structure, and the Cu (II) atom is tetracoordinated to form a planar quadrilateral structure. The Co (II) complex is dinuclear, and the two Co (II) atoms are pentacoordinated and have coordination geometries of distorted triangular bipyramid. The Ni (II) complex is a trinuclear structure, and the terminal and central Ni (II) atoms are all hexacoordinated, forming distorted octahedral geometries. Furthermore, optical properties including UV-Vis, IR, and fluorescence of the Cu (II), Co (II), and Ni (II) complexes were investigated. Finally, the antibacterial activities of the Cu (II), Co (II), and Ni (II) complexes were explored. According to the experimental results, the inhibitory effect was found to be enhanced with increasing concentrations of the Cu (II), Co (II), and Ni (II) complexes.

“…Biological activity probably conferred to them by the strong aromaticity of this ring system, which leads to great in vivo stability and generally, a lack of toxicity for higher vertebrates, including humans. Aside from these activities, Schiff bases also have other tremendous applications, they serves as dyes, agrochemicals, chemo sensor, catalyst, chemotherapeutic, anticorrosive, polymer [16][17][18][19][20][21]. Schiff bases have major concern in organic, inorganic, coordination, biochemistry and other material sciences [22].…”

A new Schiff base ligand (L) and its transition divalent metal complexes were prepared by the condensation reaction; Reaction was carried out at 70-80 oC by refluxing equimolar ratio of toluidine and aldehyde by continuous stirring for 5-6 hours. Synthesized ligand and Ni(II), Fe(II), Co(II), Mn(II) and Zn(II) bimetallic complexes were characterized by using FT-IR, UV-visible spectroscopy, AAS, Single crystal X-ray analysis, 1H-NMR, molar conductance. Compounds were screened against two fungus Candida glabrata and Candida albicans by agar tube dilution protocol. In vivo anti-inflammatory activity via induced paw edema method and in vitro results by heat induced protein denaturation method were checked. Synthesized compounds were also showed antioxidant activity by using DPPH (diphenylpicrylhydrazyl) and Trolox was used as standard. These studies show that ligand and almost all metal complexes are reactive towards biological assays against reported standard drugs. Zn-L indicates more activeness for antioxidant activity and free ligand while Co-L recognized as more effective anti-inflammatory drug.
