Abstract

The title organic ligands (Hsip) gave, by reaction with d¹⁰-metal acetates, complexes of the type M(sip)₂ (M = Zn, Cd, Hg), in which the ligand behaved as terdentate, producing a distorted octahedral environment around the metal. The ¹H and ¹³C chemical shifts found for these complexes in DMSO are compared with the corresponding ones of the free ligand. The crystal structure of the zinc derivative has been determined from diffractometer data to R = 0.072 for 1086 independent reflections. Crystals are monoclinic, space group C2/c, with unit-cell dimensions a = 18.193(2), b = 24.532(6), c = 11.535(2) Å,β = 103.71(1)° and Z = 8. Coordination occurs through the carbonyl oxygens (Zn−O = 2.10, 2.16(1) Å), the azomethine nitrogens (Zn−N = 2.04, 2.07(1) Å) and the pyridine nitrogen s(Zn−N = 2.24, 2.26(1) Å).

The Co(II), Ni(II), Cu(II) and Zn(II) complexes of aroylhydrazone of quinolone core: Syntheses, characterization and evaluation of antimicrobial and antitubercular activity
2021, Inorganica Chimica Acta
Citation Excerpt :
The signals of 13C NMR spectrum of the ligand observed at 159 and 168 ppm were assigned to the quinolone > CO and –HN-C(7) = O carbon atoms, respectively. These peaks have undergone a slight shift in the complex because of the variations in the electron density due to the coordination of the neighboring oxygen atoms [30]. The other aromatic and aliphatic carbons were observed in the expected region and are detailed in Table S3.
The ligand 3,5-di-tert-butyl-2-hydroxy-N'-((2-oxo-1,2-dihydroquinolin-3-yl)methylene)benzohydrazide (H₂L) and its Co(II), Ni(II), Cu(II), Zn(II) complexes were synthesized. The ligand and its complexes were characterized by various spectro-analytical techniques including IR, ¹H NMR, ¹³C NMR, EPR, electronic spectroscopy, and elemental analysis. In addition, the molecular structures of H₂L, [Co^II(HL)₂] (1), [Ni^II(HL)₂] (2), [Cu^II(HL)(Cl)(CH₃OH)] (3), and [Cu^II(HL)(H₂O)(CH₃OH)].ClO₄ (4) were unambiguously established using single-crystal X-ray structure determination. However, the Zn(II) complex was characterized based on the IR, NMR and elemental analysis and the 6-coordinate with a 1:2 (M:L) ratio was proposed with the molecular formula [Zn^II(HL)₂)] (5). The synthesized compounds were investigated for antimicrobial and antitubercular activities. The copper(II) complex 4, has shown the lowest MIC of 0.4 µg/mL, against the gram-positive S. Aureus microorganism, which was better than the ligand and the standard Ciprofloxacin drug. Except for the complex 3, the ligand and rest of its complexes exhibited better activity against gram-negative, E. Coli with the MIC values ranging from 0.4 − 0.8 µg/mL and were much better than the standard Ciprofloxacin drug
Electrochemical synthesis and crystal structure of cobalt(II), nickel(II), copper(II), zinc(II) and cadmium(II) complexes with 2-pyridinecarbaldehyde-(2′-aminosulfonylbenzoyl)hydrazone
2008, Polyhedron
A new hydrazonic Schiff base ligand, 2-pyridinecarbaldehyde-(2′-aminosulfonylbenzoyl)hydrazone (HL), has been prepared and characterized, and its coordinative properties were studied. [ML₂] complexes, M = Co, Ni, Cu, Zn or Cd have been synthesised by electrochemical oxidation of the anodic metal in a cell containing an acetonitrile solution of the ligand. The compounds obtained have been characterized by microanalysis, IR, NMR and UV–Vis spectroscopy, mass spectrometry and also by X-ray diffraction. The structural studies show that the metal is in a distorted octahedral environment with the monoanionic ligand acting as a meridional tridentate (N,N,O) chelate system.
A theoretical study on N-phenyl-N′-(2-thienylmethylene)hydrazine
2007, Spectrochimica Acta - Part A: Molecular and Biomolecular Spectroscopy
The molecular geometry and vibrational frequencies of N-phenyl-N′-(2-thienylmethylene)hydrazine (C₁₁H₁₀N₂S) have been calculated using Hartree–Fock and density functional method (B3LYP) with 6-31G(d) basis set. The optimized geometric bond lengths and angles obtained using HF and DFT (B3LYP) are in agreement with the experimental data. B3LYP method seems to be appropriate than HF method for the calculation of vibrational frequencies and geometrical parameters of the (C₁₁H₁₀N₂S) compound.
