“…Similarly, the magnetic moment values (3.31 B.M., 3.20 B.M.) also support this environment around Ni (II) ions [27]. Cu (II) complexes in their electronic spectra show an absorption band at 13146 and 13233 cm -1 that can be assigned to 2 T 2 → 2 E transition of tetrahedral geometry.…”

Two Mannich base ligands, [1-(di-n-butylamine-N-methyl)mercapto-1H-benzimidazole] (L 1) and [1-(diphenylamine-N-methyl)mercapto-1H-benzimidazole] (L 2) have been synthesized and further reacted with Co(II), Ni(II), Cu(II) and Zn(II) ions to afford their respective complexes. The progress of the reaction was monitored by thin layer chromatography. The structural elucidation of Mannich base ligands and their metal complexes was done by Fourier Transform Infrared (FTIR), UV-Visible, Nuclear Magnetic Resonance spectroscopy (1 H NMR & 13 C NMR) and Atomic absorption spectroscopy (AAS) / Inductively coupled plasma emission spectroscopy (ICPES). FTIR and NMR studies supported the monoanionic bidentate coordination mode of L 1 and L 2 while tetrahedral geometries of metal complexes were proposed on the basis of AAS/ICP, magnetic moment and electronic spectroscopic data. The synthesized compounds were also investigated for their luminescent behavior which exhibited broad emission bands indicating charge transfer nature of the involved transitions.

“…These possess a vital role in organic, inorganic, medicinal chemistry and biological field owing to their structures; furthermore, these have an imperative role in the theme of coordination chemistry, particularly in the development of complexes owing to its facility to produce stable organo‐metal compounds with transition metal ions. Schiff bases and their complexes are versatile extensively used for industrial goals and expose a contrasting broad range of biological activities include, antifungal, antibacterial, Anti‐leishmanial, anti‐molluscicidal, antimalarial, anti‐proliferative, anti‐inflammatory, antitumor, anti‐amoebic, antiviral, antioxidant and antipyretic properties. The Schiff base ligands derived from o ‐vanillin connected with Pd atom forming metal complexes showed a cytotoxic effect on three cancer cell lines: breast (MCF‐7), lung (A549) and ovarian (SKOV3) .…”

Complexes of VO 2+ , Co 2+ , Ni 2+ , Cu 2+ , and Zn 2+ ethyl-6-ethyl-2-((2hydroxybenzylidene)amino)-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxylate were synthesized and characterized via different spectroscopic techniques.The whole results declared that the complexes assembled in 1:1 mole ratio furthermore, the spectroscopic data analysis proved the present ligand adhered to the different metal ions in neutral or monobasic tridentate ligand via azomethine nitrogen, carbonyl oxygen atoms and protonated/deprotonated phenolic hydroxyl group. The UV-Vis. and ESR spectroscopic data analysis proposed a distorted octahedral or octahedral structure for all complexes. The ESR spectra for Cu 2+ complexes (5-6) revealed an axial symmetry with g‖ > g ┴ > g e , denoting to distorted octahedral Cu 2+ complex and the free electrons in the M shell exist in a d (x2-y2) orbital with a remarkable covalent bond aspect. The synthesized complexes showed moderate to superb fungicide activity. All complexes are more active than both standard drug and ligand against C. albicans where complexes (5-7) are more active against A. flavus and compounds (1), (4-5), (7) against S. cerevisiae whereas only complex (6) is more active against A niger.

“…The weak peaks observed in the region of 1600-1300 cm -1 are caused by C-O, C-H and aromatic ring vibrations. The band that appears at 750 cm -1 can be assigned to the C-H bending vibration of O-substituted benzene [25]. In the complex, the band between 1300 cm −1 and 1200 cm −1 is ascribed to C-O-C symmetric stretching mode of vibration.…”

Zn Schiff based complexes with high conductivity were synthesized with a facile approach at low cost. As dye sensitizers, Zn complexes have been attempted to construct dye sensitized solar cells (DSSCs), along with vertically aligned ZnO nanowires as a scaffold and an electron transporting layer for more dye load and better electron transporting pathways. The power conversion efficiency was examined by the I-V curve. Compared with the solar devices based on conventional TiO 2 nanoparticles with an efficiency of 0.815%, the solar cells with ZnO nanowires outperform greatly, with a much better efficiency of 3.68%, which holds a great potential for the widespread applications in dye sensitized solar cells devices.
