“…However, in the spectra of all the macrocyclic complexes, these bands disappear and strong bands due to coordinated v(C=N) vibrations in the range of 1610-1625 cm −1 appear suggesting the deprotonation and formation of a macrocyclic framework. 21 This contention is further supported by the presence of bands at 1465-1495 and 1355-1390 cm −1 , characteristic of a benzil moiety and may be assigned to v asym C 6 H 5 and v sym C 6 H 5 , respectively. An important feature is the appearance of a new band of medium intensity in the range of 420-445 cm −1 , attributed to ν (M-N) , which provides strong evidence for the coordination of the imine nitrogen to the metal ion.…”

“…Recrystallization of the coloured crystalline products was performed using the same solvent and the crystals were dried in vacuo. Metal complexes of Pd(II) and Cr(II) with the above synthesized ligands have been reported, 21,22 and the present work seeks to expand the range of metal complexes of these ligands by looking at complexation of Co(II) and Zn(II). The synthetic route towards the ligands is shown in Scheme 1, and the analysis and physical properties of these ligands are given in Table 1.…”

A series of Zn(II) and Co(II) complexes have been synthesized by template condensation of bis(benzil)-4-chloro-1,2-phenylenediamine and bis(benzil)-4-fluoro-1,2-phenylenediamine, respectively, with 4-chloro-1,2-phenylenediamine and 4-fluoro-1,2-phenylenediamine in the presence of transition metal chlorides. The complexes have been characterized by physicochemical and spectroscopic techniques. Based on these studies, an octahedral geometry has been proposed around the metal ions. The newly synthesized ligands and their metal complexes have been screened for antimicrobial and anticancer activities. The in vitro cytotoxicity towards the HeLa cell line has been evaluated by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay.

“…(2) Antifungal Activity . The efficacy of the synthesized complexes was evaluated against two of the fungal strains Fusarium oxysporum and Aspergillus niger using the agar plate technique [ 19 ]. In the current technique, potato dextrose agar media is prepared consuming 20 g starch, 20 g dextrose, and 20 g agar-agar dissolved in 1000 mL of distilled water.…”

We present an inclusive characterization of the unimetallic and heterobimetallic complexes of copper synthesized using CuCl2 and diamine (4-fluoro 1,2-phenylenediamine) resulting in monometallic complex which further undergoes treatment with organometallic dichlorides of group 4 and 14 in 1 : 2 molar ratio resulting in heterobimetallic complexes. These complexes thoroughly characterized using various physical, analytical, and spectroscopic techniques indicate square planar and distorted octahedral geometry for the synthesized unimetallic and heterobimetallic complexes, respectively. These complexes were evaluated for their antimicrobial efficacy against various bacterial and fungal strains while hepatoprotective activity was also examined in male albino rats.

“…derived from the macrocyclic ligands in the presence of CrCl3•6H2O. The ligands and their complexes have been characterized in different physical techniques and evaluated for their pesticidal, nematicidal and antimicrobial activities [10]. Nickel(II) complexes of substituted dibenzotetraaza- [14]annulenes have been synthesized by template reactions starting from either 1,2-diamines with β-diketones or 1,5-benzodiazepinium salts in the presence of Ni(II) contain symmetrical macrocycles [11].…”

Template method reaction of SnCl2•2H2O or SnCl4•5H2O or CoCl2•6H2O with 3-aminopropyltriethoxysilane and salicyaldehyde have been carried out to prepare three metal complexes; C32H53N2O8ClSnSi2 (A), C32H53N2O8Cl3SnSi2 (B) and C32H52N2O8CoSi2 (C). The prepared metal complexes were characterized by analytical techniques viz., FT-IR, 1 H NMR, UV-visible, CHNS elemental and molar conductivity. The analytical data shows that the metal ion to ligand (Schiff base) ratio in the prepared complexes was in 1:2. Octahedral structures were proposed for A and B complexes while C complex has a tetrahedral structure. The antibacterial activity of metal complexes were investigated against Streptococcus pneumoniae (Gram-negative) and Proteus (Gram-positive). The results showed that all the prepared complexes diminished the bacterial growth.
