Synthesis, spectroscopic characterization and comparative DNA binding studies of Schiff base complexes derived from l-leucine and glyoxal

Synthesis and evaluation of antioxidant and antimicrobial activities of Schiff base tin (II) complexes

“…Schiff base complexes catch researcher's interest due to its significant role in biologically important species and in the bioinorganic chemistry development [12,13]. The carbon having chlorine atom in l-2 showed signal at 130.63 ppm.…”

SYNTHESIS, SPECTROSCOPIC, ANTICANCER, ANTIMICROBIAL AND ANTIOXIDANT STUDIES OF HOMO-BINUCLEAR Cu(II), Co(II), Ni(II) AND Mn(II) COMPLEXES WITH POLYDENTATE SCHIFF BASE LIGAND.

“…The TGA curves of homo-binuclear Cu(II) complex exposed that it decomposed in two thermal steps. The first decomposition peak occurred in the range 70- 1 H NMR spectra of the Schiff base were recorded in d6-DMSO. The 1 H NMR spectra of the ligand demonstrated a multiple within the range 7.3-7.7 ppm which was assigned to aromatic protons.…”

“…Nitrogen and oxygen containing privileged Schiff bases and their metal complexes played a vital role in the progress of coordination chemistry ensuing in a substantial number of publications, ranging from pure synthetic work to physicochemical [1] and biochemically significant studies of metal complexes [2][3] and also establish wide range of applications. Polydentate Schiff bases have been generally used as ligands, since they can be simply attached to metal ions due to the formation of highly stable coordination compounds.…”

“…The plausible geometry of Schiff base and its binucleating metal complexes were examined by means of elemental and thermal analysis, molar conductance, 1 HNMR, UV-Vis, IR, ESR and mass spectra. From the spectral studies, a six coordinate environment around the metal dimers was confirmed.…”

Preparation of Salen–Metal Complexes (Metal = Co or Ni) Intercalated ZnCr-LDHs and Their Photocatalytic Degradation of Rhodamine B

“…In the IR spectra of all LDHs, the broad absorption peaks appearing at about 3400 cm −1 can be attributed to the stretching vibration of hydroxyl groups in the LDH layers and interlayer water molecules. For SalenCo (a), the characteristic absorption at 1635 cm −1 was assigned to C=N stretching of imine bond [29]; the absorption peaks at 1400 cm −1 and 1545 cm −1 were assigned to the symmetric and asymmetric stretching vibrations of C=O bonds of -COO-groups [30]; the disappearance of the characteristic bands at 1700-1800 cm −1 indicated that -COOH groups were completely deprotonated [31]. In the case of SalenNi (a), the IR spectrum was similar to that of SalenCo.…”
